After a trauma I went through I experienced similar. It was scary because someone woukd ask me a question, I answeted but had no idea how I knew how to answer because it was like I was watchong myself in a movie & the person was asking the question in the movie, not to me. My pdoc explained that what I was experiencing was depersonalization.

10 years + after the trauma I am much better. Now I just get a spacy feeling when I get stressed.

My current psychologist said those experiences are our coping mechamisms to deal with stress. They only are considered a real problem if they cause us problems functioning on a daily basis.

It is a scary feeling when it first hits & we dont know what in the world is happening
