What are your sleeping conditions?

Absolutely no noise or light and that about does it

I just close my eyes, then sleep. Nothing special needed.

Cold helps me sleep when I want to. And so does circulating air. When I don't want to sleep warm makes me fall asleep. It sucks in the warmer months while I'm in class and when I'm camping. So hot...

If I have a long sleeve shirt and long pants I can sleep most anywhere even without covers or a pillow. But I prefer a pillow and a heavy [weight-wise] blanket.

The one thing I do is rub my feet together. It relaxes me, and I need my fan on.

i need a punch in the face

I just play my PSP or DS till i get sleepy.

As long as it's cold, quiet and is a bed (can't sleep anywhere but a bed) then I'm fine.

My bed must be warm in the winter and cool in the summer. I usually don't like complete darkness, it bothers me. All I really need is a soft pillow, a comfy bed or couch and I'll be fine.
I can't sleep with my closet doors open, I don't know why, but it bothers me.
Lately, I've been laying in bed with a lit candle by my side , and I draw or write, or just think until I fall asleep.

Cuddles are the greatest thing though, too bad I'm not getting any D:

Cool, dark, and better damn as well be fucking quiet.

Because if it isn't fucking quiet, the CS gas grenades come out. No warnings.

Practically this, except for the gas grenades of course :D

I would add a cover and a nice comfy pillow. Most importantly, if for some reason I saw something hentai related and start feeling kind of...anxious, I need to get that out of my system before going to bed (not kidding).

That'd help wonders <3

I lay down on my bed, maybe watch some tv and then sleep. I might also just sleep directly.
Sound can be annoying but I can still sleep. Light gives me no problem with my sleep.

No stress~! Doesnt take me much to get my fucken 12 hours~xD Seriously, that or physical labor that then I get to relax in a shower (which makes me feel surprisingly refreshed~) then Im in heaven when I sleep~

If you're sleeping 12 hours a day then you should pencil something in for 2-4 hours before or after you sleep that you can do. Better to do something than to waste that time on sleeping, and 10 hours is the recommended amount anyways.

Before going to sleep I always listen to japanese music, mostly anime op/ending ones while doing some quick sketching then afterwards after I can't sketch anymore I go to bed, then I wake up at 3 in the morning to drink milk and go back to sleep to wake up again at 6 am to make breakfast.

After my stay in the military all I need is go over the table of elements in my head and I'm out..standing,sitting,lights on,lights off,hot,cold,quit,or noisy I'm pretty much dead

For me it's very very very hard to fall asleep, nowadays. The most important factor seems to be to try to be as tired as hell, by the end of the day.
