In the half-awake state I sometimes have the impression of seeing
something that is not actually there. Sometimes it is like an insect
crawling over the wall(if my face is turned towards the wall) or an
indefinite shape hovering in the air(if I happen to be turned towards
the room). This will happen sometimes when I'm almost falling asleep,
when I see it I will be frightened for a few seconds, but after that I
will be fully awake again and realize that it is not real and the
vision disappears, my sight returning to normal. I experience no such
things when I'm fully awake. I had this phenomenon happen to me before
I started taking Ayahuasca but I have the impression that it became
worse after taking it. The first time I remember it happening was
years ago after I stopped taking Risperdal(I didn't have anything like
this before Risperdal), so the latter might have caused it. I never
took any other "brain" drug/entheogen/psychedelic besides Ayahuasca
and Risperdal. Do you think this could be a symptom of HPPD?
I heard that this could be explained by being hypnagogic hallucinations(https://en.wikipedia...wiki/Hypnagogia). Is this a symptom of HPPD?
I've now stopped taking Ayahuasca for months and it seems that I'm having less of these hallucinations, although I'm not sure about it(this is all very subjective, no hard data).
