Whose world?

So what if I told you the world is a dream
A memory of things you have already seen
Visiting places you've already been
Until the day we die.

What if I said, its all in your head?
You're reliving things you thought you'd forget
Visiting life, before you were dead.
Then are we really alive?

That eerie sense of deja vu
Or wait a sec, "Dont I know you?"
Feeling like you know what to do
In what should be an aukward scene...

So tell me then, what would you do
If someone told you it was true
You're caught in the recurring view...
Of your life... as a dream?
