The final segment of my Criteria 9: Dissociated series is Derealization. Derealization: is an alteration in the perception or experience of the external world so that it seems strange or unreal.
Or another time, I was simply driving home in the late afternoon. The sun was low enough to be just over the horizon. There were trees closely spaced on the side of the road. As I would pass each tree the sun would blot out, then flash bright as I drove past an gap. From my peripheral vision I would see flash bright, dark shadow, flash bright, dark shadow like an old 8mm film reel being played on the edge of my vision. It made me feel almost as if I was floating.
It’s never an out of body experience or anything such as that. I always maintain a focus that I am doing whatever it is that I’m doing, but my perception is hyperfocused and surreal.
