Hello, rabbits, and welcome to Psych Central! I've experienced dissociation to the point where I couldn't feel my body when I was lying in bed. It's like it didn't exist.
I'm not sure what's happening with you, but it could be an extreme form of dissociation, I think. It's worth mentioning to your doctor to see what's happening for sure. Perhaps all your experiences hearing about people in trouble have affected your perception. I doubt it's an actual physiological (neurological) problem, though.
Again, welcome!
