•Bro sleeps like a log and does not wake up easily. He normally starts straight and shifts slightly in his sleep but doesn't move around alot unless his dream is a bad one. If he is having a bad dream he thrases around alot and has woken up from them by falling off the bed a few times. Likes cuddles and will go either way on big or little spoon but prefers little more. Will use anything as a pillow.

•Bro is stiff in his sleep. Like if you didn't know him and you found him while he was asleep you would think he was an actual corpse. I feel like he doesn't move around at all maybe kicking his feet out and occasionally shifting his legs. Likes cuddles but wakes up pretty early so you'll be woken up too if you fall asleep in his arms. Prefers big spoon because his height. Isn't a very heavy sleeper and wakes up fully aware like a weirdo. Uses one or two super soft pillows.

•This man moves around A LOT. He's constantly switching positions he's a very active sleeper good luck sleeping next to him and not being kicked. The only thing that really stops the activeness is cuddles wether with a pillow or a person. He's a big cuddler and 100% prefers little spoon. Being held with his head against someone's chest is one of his favorite places to be. Pretty heavy sleeper but wakes up to loud noises. Jumps awake if woken up and his normally frantic when he does searching the room for threats. Pillow King he has so many pillows.

•A pretty average sleeper he doesn't move around too much but shifts every now and then. He's normally most comfortable sleeping on one of his sides and he uses a single pillow. Isn't big on cuddles but if you're super close and have been in a relationship for awhile he is the big spoon no argument. It makes him feel like he's protecting you in a way. A light sleeper he wakes up periodically throughout the night over little things. In his part of the underground you had to be on edge constantly.

He moves around in his sleep but he's not as active as some of the others maybe switching positions completely every few hours. I feel like he'd lay on his non-existent stomach and sleep that way alot. Loves cuddles and is half and half on big and little spoon he doesn't really care. Loves to hold and be held he just wants them cuddles. He has 3 pillows two soft and one hard. He's a decently light sleeper and has nightmares as well that keep him up often so some days when he's asleep he's actually passed out no waking him up but generally a decently light sleeper. Is groggy when he wakes up and doesn't talk much.

He actually doesn't move around that much in his sleep but when he does he MOVES. Goes from one position to the next in seconds and then is like that for the next fews hours till he moves again. He enjoys cuddles a lot and will move alot less when cuddling but still somehow turns himself completely upside down while holding someone/being held. Prefers big spoon as it makes him feel bigger but he likes being held occasionally too. He's not a heavy sleeper but he's on the harder side to wake up and is a little out of it when he does.
