When I have deja vu, I just stop for a moment. It causes me to intently think, and my mind stops.
Sometimes, I may have never been in this place before. But it all feels so familiar. Whether it is the way that the light is shining down, the arrangement of something, or just the general atmosphere. It is the oddest feeling, because sometimes I know for a fact that I haven't been there. But also, I think that sometimes I have been there, possibly in my childhood.
The perfect timing of time, place, and the circumstances trigger some type of response.
After reading this theory, I definitely see the possibilities. These places could be a connection to some place I have been in the future, and everything lines up for me to feel as if I have "already" experienced it.
And it can also be for the past. I haven't had Deja Vu in a while, because I'm at college now, and not much triggers it, but I am really going to be on the look out when I go back home.
Very interesting, thank you for the bump, I would have never read this otherwise.
