Do you ever feel like you've met somone before but they're really a stranger?

[The Wilting Rose]

Because I'm getting this very strong feeling I've met this person before, and when I look at their eyes it's like I know them...just can't explain it. I know it's not normal...but dont know what this feeling is.

Have you ever felt that way before?
.... (x_x) o..k.. I was hoping for you to elaborate maybe. Also what do you think it is?
