Not really sure if this should go here or not.

My T was trying to help me cope with some bad memories the other day. She asked me to find a "safe place" and asked me to just relax and envision that I was there. That was simple enough, I let myself sort of drift out and it was nice.

She turned on the light bar, and it wasn't too bad at first, just a nice sort of "ticking" motion, back and forth. But then, I felt this horrible sensation. The only way to describe it is like being pulled away. My vision got dark and hazy around the edges, I went numb all over. It was terrifying.

My T kept asking me over and over if I had dissociated, but how do you know? It was so terrifying, and I don't know if I want to do that again. Has anyone ever experienced anything like this from a light bar? I had no idea what to expect with it, and this just seemed so strange and profound that I really need to know!
