Waking dream

The last three nights I have had real trouble sleeping. I have had about 2-3 hours sleep each night. Most of my day at work I am slipping into a trance-esque state and then suddenly realising what is going on a few minutes later. I almost feel like William S Burroughs and I am waiting for the hallucinations to kick in! I cant work out why I am not sleeping. I haven't been to the gym for a while due to my busted back, so that might be it. I am starting to feel a little bit down in the dumps over a few things, and I cant work out if I am not sleeping because of this, or I am thinking about this because I am not sleeping? It is very annoying. I am someone who loves their eight hours a night, so with anything less over a period of time I become as useful as an elbow on a crowbar. I seem to be dwelling in my past a lot, think about things that have happened and how I could have changed them or if events would have played just the same. Hell, when you cant sleep you need to think about something. I used to suffer from insomnia when I was younger but I haven't had it for years. Perhaps it is just the adjustments I am making in my life at the moment?

I have just read back this post and realise that it rambles all over the place. A bit like me at the moment!
