Yes, the mysterious workings of the brain may account for certain unusual "intuitive" experiences. But what type of brain mechanisms could account for precognitive dreams?

Interesting article here ...

There are scores of parapsychology journals and thousands of books at the Library of Congress. However, we almost never see any mention of all these immense labors in Science, Nature, or even the more adventuresome New Scientist. Why? Mainly because logical positivism, which rules the thinking of mainstream scientists, insists that the only acceptable observations are those that can be experienced by all persons. And we don't all have precognitive dreams, or, if we do, we don't recognize them as such! In addition, anecdotal data, dreams, channeled information, and the like are always viewed with suspicion.

Since few of us have precognitive dreams, the rules of science would have to be changed if they are to be embraced by science.

Well, I won't be holding my breath on that one!

I have my doubts about the assertion "Since few of us have precognitive dreams ...". I suspect everyone has precognitive dreams, but only a few remember them upon wakening. People can train their minds to remember dreams quite easily, if they want to -- but not everyone is aware of this, and even when they are aware of it not everyone wants to.

Scientists are still at a loss when it comes to understanding/explaining dreaming at all, let alone precognitive dreaming! Dreams are a universal human experience, but dreaming is still very much unknown territory. And unknown territory can prove so very dangerous to a person's comfortable, well-established belief systems, only a few of us will risk 'going there' at all.
