White noise doesn't bother me. I used to always have my computers running in my bedroom, so that was quite a bit of sound. I can also sleep well in a mostly quiet place too. When I first moved into my house, it was far enough away from highways and stuff that it was a bit too silent, and that took a couple days to get used to.
Now fans. Nope. The air moving keeps me awake. Plus, I'm one of those Always under the Blankets types. Even in summer, I'm under the heavy blanket. So cold air is right out. Even a ceiling fan on low is too much air!
I also seem to need a light. Like in a hotel, I leave the bathroom light on with the door almost closed, seems about right. At home, the light above the stove stays on. Part security so there's always light visible outside the house and inside there is some light to see by. Some of it is comfort, especially in a strange place...wake up in a pitch black room and not remember where you're at is kind of frightening.
(I just lost some Man Points there, didn't I?)
