It takes me a couple hours to watch a movie, a couple days to read a book. I can re-watch the movie or re-read the book, and enjoy them again even though I already have. The plots won't change; they are predetermined; nonetheless, I am entertained on repeat consumption.
A suitably advanced entity could do the same: consume the entirety of my life (for whatever purpose, entertainment), its trials and tribulations, as easily as I do a book or a movie. A century of time would be a small nothing to an entity who could intake 100 quadrillion fps to my 35 fps. It could "play" my life for its amusement as easily as I play a DVD.
That said, the experience of déja vu, re: predetermination, will never stop giving me the creeps.
I have long attributed déja vu to a peculiar looping phenomenon in the mind. It's hard to describe. I don't have any real facts to base it on, just that when I experience it I often "skip down" a few more levels and revisit earlier times I had déja vu. It feels like recursion of neural pathways or something. It does make me feel strange, but I try to enjoy the ride when it happens.
It's that I can see the future for a few seconds that bothers me most. Not the “I've been here before” but the “I've been here before and I know what happens next” and that exact thing happens. It's that few seconds of clairvoyance I find superitchy.
I'm fairly rational, however. I'm sure there's an explanation that's not magical.
I've never felt a sensation of peering into the future. I can see it as a possibility depending on which end of the phenomenon you're processing first, the actual event or the repeated signal.
