I read a book called 'The Celestine Prophecy'. It was about inner energies, interactions with the outer world's energy and the causes of our minds and thoughts.

It mentions deja vu a few times [convenient isn't it?], and one of the possible arguments actually applies to me a lot.

I never have a deja vu about anything significant. It's always trivial. But without exception, a similar but not identical experience will take place in the near future [minutes to an hour]. It feels relaxing for some reason.
