Hello. I am currently not a sufferer (i don't think) of hppd, but there are some things I've noticed that make me concerned that I am in the early stages of getting it.

To start this off, I smoked for about 2 years, not very often, but still have smoked weed. The drug that I am concerned about giving me hppd is MDMA. I took MDMA at a music festival in june. When I was rolling, I threw up about 30-40 minutes after ingesting a capsule of .15 gram tested MDMA. I was anxious about rolling so i went into it scared, and was anxious on the pill (no surprise there). After a while I had a great time and eventually it wore off about 6-7 hours later. While on MDMA I saw halos around the moon and lights and colors were mor vibrant. The stars in the sky were glowing more and it looked like people were walking in slow motion. I was full of energy after my throwing up and anxiousness and loved the moment i was in and my friends. The next day I didn't feel down, I was actually energized. I saw a halo around the moon the next night... never have seen that again though. That night however, I felt myself come down and was feeling blah and had very bad anxiety. This anxiety lasted 2-3 days. Than a week later I had my first panic attack. A week after that panic attack, I had no anxiety... until i went out with a friend. I drank a lot, smoked, and ended up being delusional. I believe i had a panic attack from the dab pen i smoked. I thought i was dying and kept telling my friend to tell my mom i loved her and if i got any worse take me to the hospital. From that night on i suffered EXTREME anxiety. I had DR/DP, dizziness, and nose/head pressure. One day i was so freaked out sitting in my car, I looked up at my house and saw my roof cave in like it was breathing. This has been the only time I have ever seen anything "breath". This all went away eventually besides the anxiety. In august, i believe i began to notice eye floaters. I've never had eye floaters before in my entire life. I still see them outside in the sky or against a bright light or if I'm out in the sun. They are not in my field of vision constantly. I also noticed halos around street lights, traffic lights, car lights. I feel as if this is normal however but just thought I should mention it. No visual snow but i am noticing visual noise that i believe everyone see's because I'm hypersensitive and looking for it. Randomly i have seen a line of light appear in my vision, this recently started this month as well. And during class I have seen a light form around my professors if they are standing near a white board and when i move my eyes the figure of their body appears in the "light" that i saw. this only happens occasionally however. Also my eyes hurt by the end of the day, I can't tell if its because I am staring at my computer/ phone screen all day googling my symptoms. I have OCD now trying to figure out If I should be concerned or not. 

Going to get my eyes checked today about the floaters... but need advice on if I'm developing hppd. I am afraid I am going to wake up one morning and its just going to be there. Im not a heavy user in drugs. Literally only took MDMA once. 

what were you symptoms before the full blown hppd? were you smoking weed during the mild symptoms you had before the full blown hppd?
