yeah, isnt it called as DEJA VU ??? and i also think that in my childhood it was more prevalent than now, like Phenom says. maybe children have more powerful minds?

ALTERNATIVE THEORY: we live in a simulation, and its just that we are seeing the BUFFER data in the RAM of whatever is running the sim. thus we see the same thing TWICE.
