Yeah, although I may have been too aware of my body's normal distortions, it was fairly typical HPPD from what I hear. Walls breathing, tile floors becoming 3d, constant visual snow layered on my vision. I'd say my thinking became somewhat more disorganized after the experience as well. I used to be a fairly fast reader and afterwards I had to slow down and also start re-reading more. I also had a fair amount of panic attacks, even ending up in the ER once when I was 18.
