I don’t doubt it exists but I do think observation and deductive reasoning account for 80% of it. The gut feeling or intuition are a bit different.
I’m pretty good at predictimg what people I know will do but with strangers my accuracy falls way off.

I’ll suggest that time isn’t what we think it is, and some are better at sensing these, what, leaks from the future? How could you describe it, maybe something of a shock wave? The more profound and observed the future event, the more it crosses into the present, whatever you want to call the phenomenon.
So-called “ghosts” I suspect are often the same, the past lingering or leaking into the present. A particularly traumatic event is much more prone to do so, just as a future one is.
I think I read this already.
Some of QM really is strange when it comes to time. Look here for one of the clearer explanations I've seen of Wheeler's Delayed Choice Experiment (a version of which has actually been performed in the real world BTW).
Given those two, some degree of psi just doesn't seem that far out of the range of the possible to me...
