examples

I got stressed out at work yesterday, because I was stressed I started feeling numb, spaced out (dissociated). to fix this I excused myself from what I was doing, went outside for a moment took a few deep breaths. that cleared my feeling numb and spaced out feeling so I could go back to work.

I was waiting in line at a movie theater. I happened to look at the person close to me. he reminded me of one of my abusers. I felt numb, spaced out, not quite connected to my body. my wife and I left the line, went to the car and there I was able to use my grounding and other tools that helped me to feel less numb, spaced out and back connected with my body.
