I feel like psychologists don't understand hppd because it varies, not one person's hppd is the exact same. My personal belief is that hppd is mental illness or brain damage done by rcs. The brain is obviously wired differently for people who are susceptible to hppd as opposed to the people that aren't. There's a reason for that. People are born with these hallucinations not knowing what the hell they are so they say oh i have hppd. My brother has severe autism, sees static, and weird hallucinations, whose to say I am not on the spectrum just because I haven't been diagnosed, at this point it might make sense.
