How do I deal with a seriously oblivious room mate?

Ok, so I go to a really big university and apparently she was home schooled all her life. She and I get along okay but her behavior is starting to freak me out. If she watches movies on her computer she will do so very loudly. even if I'm trying to watch the tv. usually I will watch things on my laptop because "her parents won't allow her to watch tv and it makes her feel word to have it on" she's 18. Also I will be doing homework and she will start sining aria. very loudly and if i ask her to stop she will hum for hours. She also changes the temperature obsessively. I went to bed freezing last night and then woke up in a pool of sweat because she had it on 76. How do I reason with her to calm down on the weirdness?
