I know exactly what you are talking about. I have schizoaffective disorder: bipolar type, bpd, ocd, ptsd, I dissociate a little,and panic. The change in perception is def a weird feeling, huh? but that's all it is nothing to worry about; the fly thing well I got my eyes checked out and the doc just said to keep an eye on it for changes but theyre floaters or swimmers; nothing to do with your psych stuff.
