Reality and Dreams: Just a Flash

This is most recent. A little over an hour ago, me and some classmates were waiting in the elevator at the lobby in school.

Suddenly I just had this flash on my head. I don't know what came on me but all of a sudden I felt a sense of familiarity with the scene I was in. First thought came to mind is that "Parang naalala ko ito ah? Dejavu?".

It may have been one of those dejavu moments I would experience every once in a while where I foresee events in my dreams but never get to remember them until the moment those dreams come true. the significant part of the dream was that there's this pivotal character in my dream. A professor wearing glasses and seems to be in a rush to get inside an elevator.

With striking coincidence, the very same guy in my dream was just there nearby inside the lobby as well.

I don't know what's going on but I can't see the reason why there's the need for me to foresee events like this that I may likely forget for the time being. Is this a gift or is it a curse?
