Hi, I have experienced this too, it is so disturbing and unsettling... for me, I take it as a sign that I am under extreme stress, stress that I've refused to validate or have swept under the rug for too long. I am not sure what my diagnosis is, my therapists are not big on that, but the terms dissociative, ptsd, somaticized, depersonalization get thrown around a lot. When I am dissociated, my vision is strongly affected. Edges blur, colors become muted, I lose most of my depth perception, things look bigger or smaller. Perhaps this is what you are experiencing too, and it's most noticeable when you don't recognize yourself. It's a sign you've been holding on very hard. Is there a place you can go just for a moment, real or imagined, where you are grounded and safe?
