Can’t recall the name but many years ago read a memoir about a boy who was seriously abused in his childhood, end up he has different personalities, this is an extreme case.
But very often we heard people who was abused in childhood may forget all things happened completely. They can’t remember a person / incident etc.
Not because they lost memories but simply the trauma was so severe so they just dissociated from the reality in order to survive.
In some cases, they suddenly remember everything and all flashbacks drive them crazy because the truth is too pain to accept.
You heard any stories like this?
