I sleep even weirder... I try to get to sleep but I hear all kinds of very very loud noises in my head.

For example, last night I was just starting to dose off when I suddenly heard someone shout my name, then later same thing but a really loud bang, then a while later I heard a girl screaming really high pitched for about 4 or 5 seconds as if she was stood right next to me.

Strange thing is, if I just lie down planning to get up in a couple of minutes I fall asleep straight away.

Conclusion: I am completely insane
