I think from what I remember of my Wifes psychology degree its repressed memories that don't exist. Where are you reading this stuff man?, it sounds pretty interesting.
I had interpreted it as all memories. Our memories are just figments of the imagination after all, stories we tell ourselves about the past to pass the time. The past has passed and the future isn't here yet, all we really have is right now.
....Man! I don't half feel like going to do something now.
