A repressed memory and its associated knowledge and entailment is "not there" until triggered properly. To the extent that our autobiographical memories construct our sense of identity, repressed memories have been censored from ourselves. And, I think it is censored for a purpose, not because it was one too many bits of trivia to keep in ready memory. I think it is a coping mechanism like very deep and targeted denial or dissociation.

When such memories come back, it can be like a mini identity crisis. You suddenly know things that are counter to your self-identity from the moment before. Once I was able to absorb the whole picture and not recoil back into repression, it became a permanent and unpleasant part of my self. .

There can be flashbacks of related events, some of which I also might feel are remembered for the first time in a long time. Those little flashbacks might be like remembering your specific uncomfortable cafe. The overall memory recovery is like suddenly realizing I spent years in a theater of war, that happened to have such cafes in it.
