    • Even before I had HPPD I was able to see patterned surfaces morph and swirl just by staring at them for a few seconds. I don't think the power of the mind can be understated -- if you're consciously looking for visuals, you'll often end up finding them (or synthesizing them subconsciously).  My advice to you would be to try to break the habit of "testing" your vision and to stay away from HPPD forums. Reading about other people's symptoms and over-analyzing is a vicious cycle.
    • Quick update, I've been taking cbd the last couple days, came off lithium which I started taking a little over a month ago, and had a 22oz beer and the visuals were completely gone. I stared at the wood grain table at outback and normally the dark parts of the grain would move a little side to side but it didn't no matter how long I stared. Weird but awesome. I'll take it
    • I was diagnosed with mild nystagmus which I know wasn't something I had before the trip. It's kind of just the natural outlines of the pattern already on the texture comes out and lightly moves side to side for a couple seconds then stops. Definitely have to stare my way into a little trance tho lol for it to happen. If it's a ceiling with paint dots on it no pattern comes out the dots just move a little side to side. If I stare at the oven or my phone it doesn't happen ever. Just stuff with distinctive patterns, also a granite counter top I think does it slightly too
