Teknophile, first, thanks for sharing that. You'll find the TFP to be a very open-minded place. Now, there's a whole predetermination thing going on over at the Philosophy forum. But my theory is that, every once in a while, a series of events will click into place, but that doesn't mean everything is predetermined. Only that certain events are going to happen, and in fine-grained detail. As long as you don't use what you see selfishly, I believe there is no harm in trying to change things for the better.
I've had some odd run-ins with predetermination and avoidance of it, but both times my motivation was either deep-seated fear for someone else or deep-seated fear for my own safety. But I won't clutter your thread with my stories. Suffice to say that these things happen, you can divert what seems to be destined to happen, and if you do it for the right reasons, no harm will come to you.
I did some Googling and came up with some info on dream precognition that may be helpful:

So: Don't be afraid.
