Exotrauma

undefined:

Exotrauma is a catch-all for traumatic experiences that did not occur in this universe/life, but still affect a person negatively. The word is a combination of the prefix exo- (meaning external) and the word trauma.

This term is frequently used by fictives, factives, and walk-ins to describe their experiences, but it is not limited to them. It can also be experienced by singlets, including kin and immersive daydreamers.
