It sounds like you're having emotional flashbacks. You're "reliving" feelings from the past.

Most therapists (and many trauma therapists) don't really understand emotional flashbacks. Check out Pete Walker's website. It's full of information on emotional flashbacks.

Therapists are NOTORIOUS for asking if you've had a flashback but never explaining the full scope of what flashbacks are. Yes, many are visual (re: the typical notion of what a flashback is) but many are not visual. I can't say for sure that I've ever had a visual flashback, but I have had emotional flashbacks since I was very young.
