Memories that are recorded have an initial depth and upon retrieving the memory, the depth gets deeper. Trivial events, with little reason to recall, are forgotten. This explains how trauma and ptsd can create terrible feedback loops. Having lived through a somewhat damaging childhood I have chosen to not recall the unpleasant memories and have forgotten them.
