No I usually leave my door open a crack so the light from downstairs shines in a bit. I also like to have background noise, even if its just a furnace running or something. Its hard for me to fall asleep in dead silence and complete darkness.

no
the tv has to be on

Yep, it has to be dead silent and pitch black, even the lights from the TV/laptop chargers bother me. Then on top of covering them, I wrap myself in the blankets and wrap them over my eyes and all you see is just my mouth/nose.

Not necessarily, when I sleep in the afternoon I keep the window open and I put a song on replay on my stereo, it helps my sleep

.

I can sleep in almost every condition

Yep, it has to be pitch black. I have blackout curtains and sleep with an eye mask. And I must have my box fan going at all times, as I can't stand the silence.

no,the lamp from my closet is on

I don't like being the last one going to bed in my house, it freaks me out. Somehow I feel protected when one of my parents is still up and I'm still falling asleep.

I like my environment to be dark but I usually want my door open just a tiny bit so I can see what's going on outside and the room isn't so pitch black. Windows are usually closed because I'm affraid to look outside. Always pee before I go to bed because I'm scared of getting up in the middle of the night and looking into mirrors and I like when the TV is turned on downstairs, just so there's a little noise and everything isn't so silent.

Yes. I don't mind small lights, but I can't stand when the ceiling light is on, makes me feel like I'm lying in bright sunlight. Since he was afraid of the dark and always had to keep a light on, I used to wear a sleep mask when stayed over at my ex-boyfriend's, until I got him a small lamp.

Small light. But not letting the full light in until morning.

Yes, I can't sleep with ANY lights on.

Never ever. I always need a tiny light.

Yes I usually fall asleep listening to music.

Same.
