I’ve never seen people, I do see geometric objects that aren’t there sometimes but it’s in my peripheral vision, if I turn and try and focus on it, it just disappears. anything that makes a normal person more susceptible to hallucinations also make it more likely for me, so dehydration, low blood sugar, sleep deprivation, sensory isolation, some drugs and medication. Sensory overloads. Oddly enough exercise is one of the worst triggers, I’ve been worried I’m gonna pass out from all the stacking effects messing up my vision.
