I actually find this to be quite fascinating, I think we would know our self from whatever time it was we saw it. In fact I think it is possible to see someone before they become a part of our everyday life. I had this happen in a dream on more then on occasion, I would dream of a strange person and then I would meet them in real life. carl Jung felt that when we dream we often met different aspects of our own psyche. I think that is true as well. Thing is they may not look like we do physically, since they live in the unconscious.I don't think that over all I would want to skip thru time either, but I do find it cool when I dream about something or someone and then it really happens. Last night I dreamt there was someone willing to pay me a $600 bonus, I certainly hope that happens.
