Did you ever have déja-vu? The feeling that you're seeing the same things for the second time? Is this a form of time-travelling, knowing what is going to happen, but finding it out when it's already happening? What if in some way you already know what is going to happen, because you've already witnessed it? That somehow when you die, your spirit travels back into time or to an other dimension and enters your unborn body. Most of your memory has been errased completely, but every once and a while you remember certain events. If that is true, we are all time travellers in a certain sense.
