Thank you everyone for the responses. I told my therapist about this and she said she didn't know why I do that, zone out. She said that I have enough symptoms to be borderline but she isn't going to label me yet. She didn't even relate this to borderline or derealization.

She said something like there maybe something wrong with me health wise. Usually these experiences do not last long, maybe like 30 seconds to a minute and then I snap out of it. Is that normal. Gosh I am so confused right now because my therapist is telling me one thing and everyone else is telling me something else
