Did you have any paranoia? I had some sleep problems a while back, I started thinking my family was plotting to kill me. I'm not really sure what else, actually. The problem wasn't that I couldn't sleep, it's that I wasn't getting rest even though I was unconscious (still don't know what the problem is, at least I've got a band-aid on the leak in the dam). Went on for years, and there was a long period where my memories aren't clear on the line between reality and delusion.
