I sleep fine in my room. The only times I don't have problems is when I turn off my computer for the night. I'm used to the noise I guess.

When I was staying at my girlfriend's house for a week I had a hard time sleeping. She has a fishtank in her room and her grandparent's house is really old so it would make all sorts of noises during the night. Plus before I went out there she tried to scare me by saying it was haunted, and of course it worked.
