Check your sleeping bag and see if there's a hole in it.. Happened to me and explained why I was losing so much sleep... Just a thought...
The need to ever close your eyes again. You're going to stop bl<x>inking.
If it's possible, see a doctor. I lost a friend last year to a brain tumor and her first symptoms were inability to sleep. She did reach a point where she didn't even need it in her opinion, but it caused the symptoms that eventually sent her to the doctor. And of course it could be something else, even something psychological. Unless this is some weird poem or quote, and in that case....nevermind.
Oh I might point out the symptoms were spatial reasoning, sometimes forgetting words, and slightly blurred vision until the headaches started.
