Memory is a funny thing.
If we remember a thing, we are actually remembering the last time we recalled the memory and recommitted it to memory. Therefore, memory is a xerox of a xerox (apologies to the Xerox company trademark department). In short, we have “destructive access memory”. We always re-encode and overwrite memories after reliving them, which includes whatever changes or drift we might apply.
We are also very good at manufacturing memories. I imagine us ABDL types are especially good at manufacturing early childhood memories from bits and pieces. I know I’ve watched family videos… Christmas morning, age 3, for example… and changed perspective to reconstruct the memory. Eventually, I realized the memory was faulty: I had neglected to include my father, the cameraman, in the memory…
Think about memory this way. Do you visualize a place you’ve never been to before you go there? For example, my friend has invited me and my wife out to a swingers club on his birthday (for curious observation only). I’ve tried to visualize what the place looks like. Low ceilings? Stripper poles? Conversation pits? Red swatches of color every few feet? But when we go there, the reality will replace the preexisting impression. You’ve probably done the same thing. How hard is it to visualize your guess after having seen the real thing? You can’t easily remember unless you make a concerted mental note to remember the ersatz preconception. Our memories are generally efficient at storage and recall, no wasted space, very little duplication of a complete memory engram. Our minds are more focused on creating connections between concepts than they are at duplicating them.
