On Wednesday I was playing around with what I could do with Hypnagogic Hallucinations after realizing that I initiated lucid dreams with the HIT twice the days before. So in the spirit of exploration I drifted partially asleep so that I could start seeing HH, opened my eyes and sat straight up in bed. Crazily enough I managed to mostly black my vision out with my eyes open, regain it, and watch the green manatees fly under my ceiling. I didn't go back to sleep after that, so I know it wasn't a false awakening or anything. Has anyone else done this or know if this is normal?
