There's something fascinating about getting lost in memories. Especially when you sort of understand the basics of about they work - about how the brain has a "limited memory capacity, and will overwrite older files that are not accessed frequently".

There's something quite surreal about just letting your thoughts roam. Which, by itself, is one of the most bizarre concepts around. Letting your thoughts roam. Which is also a misnomer - because you don't let them roam...they do so as and when they please. All those vague sightings, smells, incidents, all flitting about going la-la-la, playing tag with each other, merging into one other, and generally giving short shrift to any attempt by you to get them to line up and be counted while you herd them back into the pen.

So...
your memories roam.
And you cannot always control them.
....doesn't that strike you as very, very bizarre? Scary, even?

And what about that feeling when this big memory-party does happen - of you being inside your head, standing slightly to the back of stage-left, watching all of this happen. How does that not freak us out? How do we go back to behaving as if everything's normal, when just a while back we could feel ourselves inside our own head, somewhere an inch diagonally upwards behind the eyes, and not know why we were thinking of what was being played out around us?

It's all mirrors-inside-mirrors, and we have no clue about what it really means. It's enough to convince one of aliens.
