1, 5, 8, 17... for the adorable one

3, 7, 16 for jace

1) how do they get ready for bed?
Shower, sleep pants, and then he reads until he gets sleepy. That's assuming he's sleeping alone, anyways.

5) do they prefer to share a bed with someone else? someone in particular, or just generally not being alone?

For the longest time, he prefered to sleep alone, because of his nightmares. Once he went to live with the Lightwoods, he'd occasionally go sneak into Alec's room and sleep across the foot of Alec's bed. Now? He prefers to sleep with someone. He loves cuddling and petting and sleepy kisses.

in what position do they sleep?
Is starfish a position? He tends to be a stomach sleeper, and spread out as much as possible, or sprawled out on top of someone if he's sleeping WITH someone.

17) do they need to sleep forever, or can they naturally run on less than 5 hours of sleep a night?

Jace is a Shadowhunter. He can get by on three hours, a cup of coffee and stamina and endurance runes, if he has to. If he gets the CHOICE, however, he'll take a solid eight hours and consider it a luxury.

3) how many pillows do they need/use?
Ideally, four. Two for his head, one along his back and one to wrap his arms around. Like I said, natural snuggler, and pillows are acceptable substitutes.

7) do they snores?
No, but he does talk/mutter in his sleep if he is absolutely relaxed in his sleep. That generally only happens if he's sleeping near someone he trusts utterly.

16) do they talk in their sleep?
See above XD

Evilsalmon

but what does he saaaaaay

Ha Evilsalmon: ha. Names sometimes. Bits from his dreams. Or nightmares. I’m sure more than one embarrassing confession about feelings has slipped out without his knowing it

is it embarrassing if probably already confessed?

If he knew he was saying it where it might be unwelcome or pressure. Yes
