Intrusion
Intrusion means "memories from the past" and is the umbrella term for flashbacks and nightmares, such as those occurring in the context of PTSD. The memories are experienced as distressing, but it is possible to distance oneself from and categorize the memory as such.
(In contrast, with a flashback, it is not possible to distance oneself from the event/memory.)
