Why do certain memories pop up when they do? What triggers that part of the brain to open a door and release an item which has been buried for years? I'm not referring to recall due to trigger devices such as a smell or perusing a photo album, but to memories that appear unexpectedly, apparently without external prompting, totally out of the blue. (But can something truly happen out of the blue? Another query for another day.)
Perhaps I shouldn't be wasting my time pondering this perceived trivial event. But when one wakes up in the middle of the night with a memory which had been formerly buried in the deepest recesses and now appears crystal clear at the forefront of one's brain, as if the event had happened just yesterday instead of decades before, it does cause pause.
Why now? Is there a hidden meaning? Is there a sixth sense phenomenon at play? Should these impromptu memories cause concern or actions or be written off as a result of deep sleep? And yet, doesn't the subconscious actively influence?
If I were a scholar, perhaps I could answer these questions....
