yea dude chill out. i dont have HPPD, but i definitely have flashes of random light, increased floaters at times, random auras, and sometimes heavy textures move. am i faking it to be one of the "god damn kinds" you speak of? nope they just happen.
A friend of mine had this poster of the girl from Evenessence in his apartment, and I became very fixated on it during one trip. It just all of the sudden seemed like the best art I had ever seen. And for about 2 weeks after everytime I looked at it I would start to trip again. Not near as intense though.
I remember my 1st flashback, I was taking a shower and for a few seconds it was like gold petals were just bursting out of nowhere and they were everywhere and just started falling like glitter. And I was like man that was weird. Then I got on with my shower
I never said that anybody was faking. I was saying that you read up on the shit & worry about it so much that you make it happen. I did it myself for a while.
