I don't believe in psychics or precognition etc. As has already been mentioned, there is always a perfectly sound scientific reason for "supernatural occurrences" - even if it is too hard for people to fully understand (e.g. the inner workings of the brain). Plainly, there is no such thing as d�j�-vu in the sense that you knew the future before it happened. And "psychics" are just so obviously frauds out to make money. Trust me, if ever there was a mind reader who could really read minds, or a fortune teller who actually saw the future, it would make worldwide news faster than the time it takes to read this sentence. That will never happen, of course, because these things are obviously not possible. You might as well believe in unicorns.
