There are people who work out things in their mind or have a dream that somehow pans out in real life. Mostly they guess, sometimes educated guess’s, but just a guess.
There is no one with true psychic abilities IMO.
I have no doubts that there are fallen angels who will try to manipulate humanity to their ends, and if they can facilitate truths and half truths about the future to gain leverage over people they will do so.
On a far more mundane basis, I also have no doubts that we have only the tiniest bit of understanding as to how the human mind actually works. Even a dullard like myself would see a glass of water precariously perched at a table edge in a house next to the train tracks and be able to "foresee" the glass falling to the floor and shattering when the next train goes by. This is not due to some mystical ability of prophecy or precognition, but merely the application of logic to knowledge obtained from previous experience: i.e, I know the house shakes when a train goes by. I know that an object perched at the edge of a table will very likely fall when the table is rattled, and I know a drinking glass dropped on a hard tile floor will typically shatter when dropped from a certain height.
These are all very easy dots to connect, but I suspect in some people and at some level of the subconscious, some much more complicated sequences are worked out such that somebody may seem to have a unique precognitive ability, when in fact they are merely arriving at conclusions based on their past experiences and logic. Moreover, as this takes place in the subconscious, the person may not even be aware of the process, but only the conclusion, and may come to believe they are actually in possession of some sort of paranormal gift...
