promnesia (s) (noun), promnesias (pl)
The paradoxical sensation of recollecting a scene which is only now occurring for the first time; déjà vu; already seen: While riding in the car, Thomas was sure he had observed the same river, the same houses, and the same people walking along the streets before although he was traveling in a perfectly new area where he had never been before and was certain that he was experiencing a case of promnesia!

Science fiction is usually where examples of promnesia are found

One of the best examples of promnesia is found in novelist Morgan Robertson's novel, Futility, printed in 1898.

Published fourteen years before the ship named the Titanic sank in history's most famous marine disaster, the novel told of a great "unsinkable" luxury liner named the Titan which sank on its maiden voyage after hitting an iceberg, with the loss of almost all of its passengers because there weren't enough lifeboats aboard.

There were at least ten other promnesias in the novel which were applicable to the real tragedy which took place with the Titanic; and remember, the novel was published fourteen years before the actual disaster!
