Precognition refers to a type of extra-sensory perception which would (if it exists) allow a person to perceive future events. In the New Age world as well as the world of con artists, such "gifts" are possessed by only the select, special few, and are therefore, likely to be pricey to see "in action".
Precognition is similar to clairvoyance, and makes a great narrative device because it brings up ideas of fate, destiny and free will — so people can be easily attracted to the idea. In the real world it is, of course, bullshit pseudoscience.

 Explanations of anecdotal evidence
Most "evidence" for precognition tends to come from anecdotes rather than any actual data — indeed, properly controlled trials show no effect. People who don't do this for a living — such as dear ol' Aunt Gladis who says she can predict the future — tend to rely on confirmation bias and selective reporting, which are both effects of the human mind recalling and confirming some instances and forgetting disconfirming others.
That is to say, dear Aunt Gladis had a dream one night that a plane would crash and the next day one did. So she says to herself "I can predict the future". And if it should happen again, for instance she dreams her son would get sick and he does, that reinforces her belief that she is "seeing the future." However, what she conveniently forgets are the thousands of other dreams that "predicted" the future, which never played out in the real world. This is because cases that don't agree aren't particularly interesting or notable — no one remarks at a lack of co-incidence. Furthermore, the worldwide frequency of plane crashes is about once every 2 or 3 days, so there's an excellent chance that there will be a plane crash within 1 day of dreaming about one.
So should Aunt Gladis be thinking of a dear old friend and then a minute later they happen to call her, she'll remark upon it, but if the friend calls her out of the blue when she wasn't thinking of them, she'll not mention the lack of a premonition. The confirmation bias effect is pretty much responsible for all reports of psychic powers, from mediumship to remote viewing. Remarkably, even apparently scientific tests can fall foul of these effects. When someone is asked to exhibit some form of telepathic power and they get it wrong, the statistical context is often brought up in a certain way to say that this sort of incorrect guessing is inevitable due to chance, or that not everyone is psychic. On the other hand, if they happen to guess correctly, the statistical context focuses on the odds that the individual has defied in order to make their prediction. For example, someone correctly guessing several Zener cards in a row has defied 100 to 1 odds for correct guessing and this is hyped even though it is a plain statistical possibility.
 Mythological precognition
Most mythologies throughout the world, address precognition in some way. Someone, usually a Hero archetype, or someone from the 'divine' realm will warn the world about some impending disaster they foresaw in a dream, or that they were warned about by some kind of mysterious otherworldly voice. Mythical figures have the added advantage of generally focusing their precognition on things that are so far in the future, no one alive can call their bluff. The Christian Bible calls it prophecy if it's from the acceptable God, and "divination" if it's from a big bad ugly god. Not surprisingly, divination is a sin, but prophecy is the work of "Holy Men". If the prophesy comes true, the old fart is hailed as a man of God. If the prophesy does not come true, it is put down as something which has a future fulfillment after the rapture.
 Hitler was psychic
historian pseudoscientist David Irving believes The Führer himself foresaw that little David would turn up and specially chose David to write about him. Despite Hitler having such wonderful psychic powers he overlooked the catastrophic defeat that followed from invading Poland and starting World War II? Well, it must be pleasant to think that you are specially chosen by God the Führer and little David might not want to spoil things by thinking it through.
 Princess Diana
Medium and general psychic Sally Morgan foresaw the road accident that killed Princess Diana a year before it happened but didn't warn the princess. Sally's powers weren't quite working, and so she thought the victim was the queen, though she didn't get round to warning the queen either.
 Science and precognition
But wait! If precognition is possible, then it must have been studied, and there must be something to it, right? Of course right — if by precognition, you mean a fraction of a second before you are conscious of your choice, a computer using live fMRI can "see" your choice being made, and predict it before you make that choice.
Other than that, the concept of precognition has been studied in the scientific context for decades and there are multiple studies that provide us with results which point that the idea of precognition should not be dismissed as hogwash and future studying - quite literally - is warranted. The implications of real world applications for precognition would be enormous, whether it's existence is universally accepted or not. Biggest criticism towards the successful studies regarding precognition is coming from two camps, psychology and physics. Physicists sometimes dismiss precognition as an impossible idea, because they believe it violates fundamental laws of nature, but especially considering the advancements in the field of quantum mechanics, precognition wouldn't necessary have to violate laws of physics as we currently define them.
The second camp of critics, psychologists, often point how difficult it is to replicate results of successful studies, small sample sizes and other flaws in methodology, despite the fact that certain paradigms of psychology rest upon similar studies with small sample sizes and difficulties in replicating the results. Due to the controversy surrounding precognition and the fact that the discovery of irrefutable proof of its existence could force us to rethink current paradigms of psychology, one does not even need to be gifted with precognition to know how even good scientific data is usually received.
