    • I am 18 years of age, i have only noticed that i have HPPD for the past 3-4 months after seeing some articles about it. i must have taken 50-60 tabs within a year and HPPD has only got worse over the past few months. Although it has not been that long it gets considerably worse over time. Its nothing to worry about as dealing with it can be accomplished but do not dwell on it and let you worry. There many never be a time when you over come in only learn to deal with it permanently and effectively.
    • @HDDeer Interesting.  Your post got me thinking.  When I was a little kid I used to see recognizable shapes in the trees between the branches.  I think it's called negative space.  When I looked at the stars I'd see cobweb like threads connecting the stars and I'd immediately see shapes.  If I stared up under the trees at night I'd see cartoon like animations play out in the vague outlines of the branches and leaves.  This was long before I had tried anything psychoactive.  I was basically a normal kid with no indication of mental illness or schizophrenia.   I'm starting to think my brain is simply wired to see patterns.  I'm wondering if these natural abilities, for lack of a better term, are indicators for contracting hppd or at least the flavor of hppd I have.  When my daughter was about 5 she made a comment about seeing shapes between branches.  My Mom has made similar comments over the years.  Perhaps there is something genetic at play. I realize none of this is concrete but your post brought back these memories and helped me connect some dots.
