Yeah, sounds like you're verging on Depersonalization-Derealization symptoms more than HPPD. Jay can probably answer this better than I, but my interpretation of HPPD was that it's mostly visual disturbances: streamers, trails, halos, visual snow, flickering, changes in color, breathing textures and surfaces, closed-eye visuals (CEVs), etc. Lots of people end up getting DP symptoms along with HPPD, and visa versa, so you could be someone who just has more DP than HPPD.
