So last winter, I wrote a sleep story about a ferry crossing, and I noticed afterward that people really seemed to like that one. And just last week, I got a very nice comment from a member of the Snoozeville community named Heidi. She told me she liked that episode, and she mentioned, just sort of in passing, that she'd just taken a ferry herself from Athens over to Crete. And I loved the sound of that. A boat crossing the Aegean at night. All those little Greek islands out there in the dark.So Heidi, I'm not sure you meant for your little comment to turn into a whole new episode, but here it is. And it really is the perfect thing for a sleep story. Being on a big ship in the middle of a warm sea, and that feeling of handing everything over, of being carried through the dark toward morning.It's exactly the feeling that we're after tonight. The steady hum of the engines, the slow rocking of the water, and the moon outside. It's designed to quiet your mind and carry you off to sleep.But first, please make sure that you are somewhere safe to fall asleep. Preferably tucked into your own comfortable bed, and not anywhere you need to stay alert. And if you're not a follower of the show yet, please think about it.It's free. It only takes a second. And it means the next episode turns up for you automatically when you need it.And now, let's get you settled. At this moment, I am assuming you are in bed. Maybe you lay down tonight, and the first thought you had was, I'm not going to sleep tonight.Maybe you were tired an hour ago. Nodding off on the couch, and then you got into bed and vanished. You were wide awake. And if that's you, you should know it's pretty normal. Happens to almost everyone. It doesn't mean that you're not tired.That wide awake feeling is a little bit of a trick, and you don't have to believe it. Because underneath that feeling, there's something very real happening in your body called sleep pressure. From the moment you woke up this morning, your body has been slowly building it.A natural, steady pull towards sleep that gets stronger with every hour you're awake. And by now, tonight, it's high. The wide awake feeling is just sitting on top of it, like a little bit of choppiness on the surface of deep, still water.So let's find it, just for a moment. Imagine that sleep pressure as something physical, a soft, heavy weight that's been gathering in you all day. It's in your limbs, it's behind your eyes, and it's been waiting all this time for you to lie down and let it take over.So let's take a few slow breaths, and let that sleep pressure rise. Breathing slowly through your nose, if you can, filling your lungs right to the very bottom. And then let it out slowly, a long and easy breath out. It's that long exhale that is the signal. It tells your body that the day is done. And then again, slow breath in, and then a longer, slower breath out.Nice. One more time in, filling your lungs, and then out, letting everything go with it. And then just let your breathing settle into its own rhythm.And we'll move through your body briefly, letting each part go heavy. Then start with your face. Let it soften.Your forehead, your eyes, all the small muscles around your mouth. Let them go loose, and then feel your whole upper body growing heavier, sinking down into the bed, as if you are suddenly very, very heavy. The heaviest thing you can imagine is if you're suddenly made of heavy, wet sand.And then let that feeling of being weighted, of being very heavy, move down your arms, all the way down, past your elbows, into your wrists, and your hands. Let your hands lie open and still, empty. There's nothing left for them to do tonight.And feel your back settle. Feel every point where it meets the bed. And feel your hips let go, and that heaviness spreading down through your legs, through your thighs, your knees, down through your feet.Your whole body is heavy now, and the sleep pressure that has been building all day is there, in your limbs, in your muscles, in the corners of your mind, in the darkness. It just needs you to be still for a while. Your breathing becoming quieter. Your thoughts becoming still. And while this is happening, I'm going to take you somewhere. A warm sea on a dark night, under a blanket of stars.It is a warm evening in September, and the ferry is getting ready to leave. And this is not a little boat that carries a few cars across a river. This is a proper ship, nine decks high, long as a city block, with a great open mouth at the back where the cars drive in.It runs overnight from Athens to Crete, and tonight it's nearly full. The harbor is still holding the heat of the day, and the stones on the dock are warm. The air smells like salt, and diesel, and somewhere close by, grilled fish, lemon, oregano, drifting over from a taverna along the front. The cars are still loading. They come up the ramp, one at a time. Small dusty hatchbacks with roof boxes, a camper van, motorcycles, and a truck or two.Families who have spent the day at the beach and still have salt in their hair. A crew member in an orange vest waves each one into place, gets them as close as they can go, and calls for the next one. Among the passengers coming aboard tonight are Frank and Diane.They're in their late 60s, and they're from a small town a long way from any ocean. The kind of place where people don't take trips like this. They talked about it for 40 years.Someday, they always said, and then this spring it felt like there was no more some days left to wait for, and their daughter told them to just go. So here they are. Greece.Diane still can't quite believe it, and she keeps saying so. They come up the ramp slowly taking it in. Frank has a folder of tickets and papers under his arm. Everything in order. Everything double-checked. Diane has a straw bag over her shoulder, and her phone is already out.Ready to take pictures of everything. A crew member checks their tickets at the top of the ramp, and when he sees they're a little unsure of where to go, he walks them partway, showing them the stairs. Diane thanks him twice.Inside, they climb the stairs slowly. Frank reading the little signs. Diane looking at everything.The lounges. The low lights. The big dark windows.They expected something rougher, but instead there's carpet and soft light and the smell of coffee and people settling in comfortably for the night. They find their cabin along one of the quiet corridors below, and Frank gets the key card to work on the second try, and the door opens on a small warm room. It's tiny.Two narrow bunks. A little sink. A folding table.A round window looking out at the dark. Diane says it's like a little house. Frank sets his folder on the table and agrees that it's really something.She takes a picture of it to send to their daughter. They booked it as a splurge. The extra for the cabin instead of a seat, and they went back and forth about it.The way they go back and forth about spending money, and in the end they decided that if they were going to do this, they were going to do it right. Diane is very glad they did. Together, they decide to go up and watch the ship leave.By the time they find their way back up the deck, the last car is on. Somewhere below, the great ramp at the back begins to lift. Slow and heavy, holding up and closing the ship like a door pulled shut for the night. There's a deep clang as it closes, and then the sound of it locking down. The engines change. They've been idling all this time. Low murmur, nobody noticed. Now they deepen and take hold, and you can feel it more than hear it. A steady vibration coming up through the deck, through the soles of your feet, through the railings.It's the feeling of something very large beginning to move, slowly at first. So slowly that at first it's the dock that seems to slide, not the ship. The gap of black water opens up between the hull and the harbor wall.A foot, and then a few feet, and then too far to jump. A crew member on the dock unhooks the last rope, and it drops into the water and is hauled up, dripping. And that's it.The land. Let's go. The ship turns north.It settles onto its course, and the engines find their steady note, the one they'll hold all night. And the deck begins to rise and fall as the ship meets the open water. Frank and Diane stay at the railing.There's no reason to go in yet. The night is too warm and too soft. And neither of them have ever stood on the deck of a ship at sea in the dark before.And then eventually the lights behind them begin to thin out. The land sinks down behind the water until there's nothing back there at all. Ahead and all around, the sea.And it's calm tonight. Long, slow swells. Wide and easy.The ship riding up each one and settling down the other side. Down along the hull, the sea slides past in a long white rush, folding away from the bow and trailing back in a pale wake that glows faintly, and then loses itself in the dark behind them. The night is full of stars.Out here, away from any town. Away from any light at all. There are more of them than either of them has seen in years. Maybe more than they've ever seen. The whole sky crowded with stars. Thick and pale and scattered from one edge of the sea to the other.And low over the water to the east. The moon is coming up. It's past full and it's that deep warm gold that the moon goes when it's close to the horizon. Sitting just above the sea and laying a long track of broken light across the water toward the ship. Diane takes a picture of it. It won't come out.The moon never does. But she takes it anyway. Frank puts his arm around her and she leans into him. And they stand there at the railing of a ship in the middle of a dark sea under all those stars with the warm wind moving over them and the moon coming up. After a while, the air begins to cool just slightly. The first hint of the deeper night.Frank feels her shiver and says maybe they should head in. The floor is carpeted blue and worn soft down the middle where thousands of feet have walked. The engines come up through it.That low steady thrum. More like a purr that you feel in your feet than a sound you hear. The whole room hums with it.The kind of sound you stop noticing after a minute and only find again when you go looking for it. The overhead lights have been turned down for the night. The lounge stretches out under them, dim and soft. Lit here and there by a little reading light someone has clicked on. Rows of reclining seats. The fabric faded.The arms worn smooth. And all through the lounge, people are settling in for the night. Near the middle of the lounge, a young mother sits with a small girl on her lap. Three, maybe four years old, in pajamas already. And the child isn't tired yet. She's watching everyone go by with big serious eyes.And as Frank and Diane pass, the little girl looks up at them. Diane can't help herself. She stops and says hello and asks the girl how old she is in English.Which the child doesn't speak. But the mother smiles and says something soft to her daughter in greek, and the little girl holds up four fingers. Diane says, four.What a big girl, and the child, deciding she likes this little girl, gives her a slow, shy smile, and then buries her face in her mother's shoulder. The mother laughs, and Diane laughs, and Frank is smiling, and for a moment, the two of them, and the young mother, stand there in the low light, being pleased with the same small thing. The mother says something else.Thank you, probably, or good night, and Diane touches the child's little foot in its sock, and says, good night, sweet girl. Sleep well, and they move on. Frank says something about how you meet the nicest people traveling, and she agrees.Down they go, into the quiet of the corridors, toward their little room, and their bed, and the round window with the moon outside it. The corridor is quiet and dim, and the carpet's soft underfoot. The door is running along both sides, close together, each with its little number. Down here, you're closer to the engines, and the home is deeper, and under it, there's the sound of the sea moving along the hall, somewhere just beyond the wall, a soft, continuous rush, and every so often, a door clicks shut, as someone turns in. Footsteps pass, and fade, and then quiet again. Frank works the key card, and this time, it takes on the first try, and they step into their little room.Frank's folder is still on the folding table, where he left it, and the two narrow bunks are made up with white sheets pulled tight, and a blanket folded across the foot of each, crisp and clean, and turned down ready, and through the round window, the moon. It's higher now, smaller and paler than it was down at the horizon, but it's there, laying its light in a broad, soft path across the water, and the water rises, and falls past the glass, coming up close enough to see, and then dropping away, over and over. Slow and steady, and they get ready for bed quietly, teeth brushed at the little sink, clothes folded over the chair.Frank climbs to the top bunk, which takes some doing, and some good-natured complaining. Diane settles into the lower bunk, and she pulls the clean sheet, and the blanket up over her. I'll never sleep, she thinks.Too much in my head, too much to see, too excited. She always thinks this in a new place. She thinks it now, and she's asleep in minutes, and on the top bunk, Frank's already gone.He's breathing slow and even, and all through the ship it's happening, one by one, and then everyone, let down to sleep by the slow rocking, the same deep hum, the same warm darkness. Because the ship does the work, the ship knows the way. It has made this crossing a thousand times, and it's making it again tonight, carrying all these sleeping people north across the dark water.Up on the bridge, someone is watching the sea. Down below, the engines turn. Steady and sure, there's nothing to do, but lie still and be carried.The moon crosses the little window. The sea rushes soft against the hull. The ship rocks them all.Slow and steady and endless. On through the warm dark, toward morning. And Crete in the morning will still be hours and hours away, and you're not on a ship tonight.You're in your own bed, but some of what carried them is here too. The stillness, the dark, the weight of your own body sinking down, and your breathing has already slowed. You didn't ask it to.It just did. Slow breath in, slow breath out, each one a little deeper. There's a stage just before sleep, a threshold you're probably crossing already, where the mind lets go of its grip.Thoughts that were sharp and connected start to loosen and drift, one no longer leading to the next. They stop being thoughts really, and they start being something more like images, a face, a color, a scrap of somewhere. They float up and float off and don't mean anything.Not drifting is the beginning of sleep. Your brain is changing gears, slowing its rhythm, moving from the fast, busy waves of the day down into the slow, easy waves of rest. You don't have to make it happen.It's already begun. So let it. Let the thoughts come loose and wander off.Let the bed hold you the way the ship held them. Let yourself be carried, same slow, steady way, down and down toward morning.
