Feelings of unreality (Derealization)

Ever get it?

why of course

Sometimes.

Yeah.

SHIIIIIIIIIIIEEEEEEEEEEEEENSUUUUUUUU!!!

All the time.

Loads of times, today in fact. I was walking the dog, but of course he was being slow so I turned around to check how far away he was and i saw his figure in the corner of my eye by a tree.
Turns out he was way ahead of me the whole time.

Maybe...if i define it right.

Sometimes I’m just walking when I notice if this I’m real or not, like how I move my hand without any thought put into it.
