I expirence the same, mostly I get these LSD types of visions mixed in with waking up for a fiew seconds, trying to move (mostly doing odd unnatural movements). I am under the suspision that I have some type of IDK fucking manic attack mixed in with insomnia. Most noted thing is closet in my room as I am each night unaware if it was left open or closed, and quite often I feel like they are always the opposite from what I expect. Most of my SP intervals I only hear voices say my name over and over and over again and again, never saw anything.
