if I try to read something while laying down, I am guaranteed to fall asleep. Also trying to think about something, like how to relax muscle strains, or sorta meditating, or self hypnosis. I don't last long.
I don't have a schedule, so sleep when I am tired, and that can be day or nite, but more often day. I don't like seeing it getting light out. Not a daytime person, so that helps me get sleeping. I could always fall asleep with the TV or radio on, and after being injured the TV on kept me from having disturbing sorta dreams. No story or images, just strange shapes and colors. They don't happen anymore, but it is easier to fall asleep with something on. Think I have always sorta been that way, unless really tired.
