I'm currently recovering from an evening of partaking in the LSD. An evening of soul-searching and deep though is the best thing that came of my birthday, and was significantly better than any and all birthdays previous.

HPPD
What a shitty disorder. Has anybody experienced this?
Hallucinogen persisting perception disorder - Wikipedia, the free encyclopedia

More like my ONLY hangover cure, besides a full day of sleep.

Yeah, I like it though. For me it just means that if I stare at anything long enough, it seems like it's moving.

I sort of get this, too. The ground becomes wavy, sometimes. If I stare at a "popcorn" type ceiling, the bumps will start to swirl like cells in a bloodstream, just like they do when I'm tripping. Do you ever see trails or glows around people?

lol, I get that if I play Guitar Hero for long periods of time.

I've had what I assume are mild flashbacks for years but they're never persisting nor are they scary or life-altering in any way. But I also always see blue halos around streetlights especially... but I can't remember if that's normal or not, because the first time I've ever noticed them was when I was during my first trip a lot of years ago and I'm assuming that in normal circumstances it's because of pupil dilation, which, at night, your pupils will be relatively dilated to allow in more light.
I also see barely perceptible trails (tracers) with bright moving objects in the dark, but again, I can't say that's not normal to a degree.

I'm guessing HPPD has to manifest at a much higher intensity before it would be considered, because I can't imagine even my flashbacks as being something someone would worry about or report to anyone out of concern.

No, but I've never seen that stuff while tripping either. I typically don't have very visual trips.

This is completely unrelated, but this thread reminds me of this thing I've seen before:

This is your brain on drugs:

Anyone notice when they smoke pot that your legs start to feel really heavy?
