G'day,

I don't remember ever saying that OBE memories are lost forever.....

But the ram analogy could give that impression, yes.

Most likely, OBE and dream memories that are not remembered stay in unconscious memory. There, they will sometimes be triggered by associations and, as you say, surface.

The human mind remembers every minute detail of life, and so its likely that obe's and dreams would also be stored somewhere.
