A premonition is an impression, often perceived as a warning, of a future event (from the Latin praemonēre, to forewarn : prae-, pre- + monēre, to warn). It bears similarities to the concept of second sight in that it frequently comes in the form of a paranormal vision or as a vivid dream.

Premonitions are sometimes attributed to the presence of supernatural or paranormal abilities such as those of the prophetess Cassandra. However, the distinction between precognition and ordinary evidence-based predictions is sometimes not made sharply. Premonition is a concept which may or may not include ordinary predictions, resulting in a bias towards supernatural explanations for the phenomenon.

There are many recorded instances of premonitions which have come true but many others may be explained by the knowledge or deduction of those who experience them. An interesting analysis is presented in J.W. Dunne's book An Experiment with Time.

when you see here Tobi said this...Naruto 453 page 18 | One Manga

he cant believe what nagato did...

every premonition (time travel) he had and everything he saw in future now changed.... now he must do something to fix it and the time is going fast for him if he dosent do nothing now he will be past and probably not do what he wanted cuz future changed , and naruto and nagato changed...

premonitions are not yet proven 100% real they are still science fiction or coincidence....

so what you think about this?
