i can't remember if you've mentioned this before. do you hallucinate during your flashbacks? i do. i relive the traumas i experienced and hear the voices of those who were responsible for them.
(sorry for the off-topic post everyone.)
Yes, although if it's flashback material, I don't know if it counts as hallucinations. I have had flashback material mixed in with hallucinations, for example once I was re-experiencing a trauma all the while feeling a rat against my arm, which I know wasn't part of the traumatic experience.
