Quoting an article in New Scientist magazine, Cleary said that the role of memory is not necessarily to remember the past, but to help us move into the future  Memory sometimes uses imagination and creation to let us know what to do next, or how to react in certain situations  Some people think that they have the ability to foresee the future, but they may be fragmented memories of the past
If the feeling of deja vu comes from an unremembered memory, it is easy to create the illusion that what happens next also comes from this memory and that you have psychic abilities
Deja vu can help us see the future.
