Not sleeping

I've only been home for around three nights. I was luckily drinking one night, so i fell asleep very easily in my old bedroom. But the past few nights it's been rather odd. I don't like it down there, it's harsh and full of memories, good and bad. I'm surrounded by a world that i had forgotten and escaped from so i could be myself in another city. I almost moved to sleep in the loungeroom, but the effort of dragging my bedding up the stairs stopped me. I tried again and managed to fall asleep at around 1am.
I want to be able to sleep in that room, but it's so very odd and i just keep thinking about being sixteen and hiding from whatever it was that i was angry or upset about at the time.
