Are there people with real supernatural ablities?

That would depend entirely on what you are truly asking.

If your idea of supernatural powers is based on examples found in written fiction (books, graphic novels, etc.), or in movie or television images, then most likely the answer is no.

There are documented cases of people who have what can be described as "supernatural" powers, such as telepathy, telempathy, telekinesis, pyrokinesis, and precognition, just to name a few.
