Why do we get the feeling of deja vu?

Answer 1

one current concept is that your brain misplaces the present into long term memory. so when you recall it as you see it, what you see seems to come from you long term memory. that would explain why you cant recall where you have seen what you are seeing. kind of a glitch in the matrix. happens me to quite often

Answer 2

Basically what happens with deja vu is the signals get crossed, the memories get all mixed up.
