Or at least that’s one way to look at it. What if a deja-vu (you know, that moment you feel you’re seeing or hearing or experiencing something you already have experienced, yet you haven’t), is actually you remembering something? That is, finding an old memory of such experience. Obviously, an old memory that shouldn’t be there.
So where would it come from? That’s the tricky part. It comes from the present, being a new memory treated as an old one. See what am I aiming to? Well, this thought led me to think a few things about our own mind and how memories work.
