Mystic Meg may say she is in contact with the spirit world but she's not really. Astrologers, clairvoyants, tarot readers make unfalsifiable claims that appeal to the weak of mind. This is neither supernatural nor paranormal, it's simply fraud. Belief in psychics and astrology is no different in nature to faith in doctors or science. Or religion for that matter.
People who get a spooky feeling of being watched by eyes that can't be seen are experiencing an actual effect that is qualitatively different from that which is experienced by someone phoning a tarot-card reader for advice on life.

The brain produces a field which can be sensed to some extent by an EEG machine. I am suggesting that that entire electrostatic field generated by the brain could be considered to be an 'aura'. It would be dynamic in nature because the movement of ions in the brain is a dynamic process. It could be that the electrostatic field can be effected by other electrostatic fields that can effect the brain at a neural level thus acting as a sensory input that can be utilised by mechanisms of the brain.
Perhaps I wasn't clear: I think that all supernatural phenomena have their roots in the physical realm and are in fact 'natural' phenomena. What I'm saying is that some people experience things that defy explanation. Things like having the feeling that you're being watched or being warned of impending disaster by a long-dead loved-one and everything in between. These things actually occur in reality, the causes of these kinds of experiences are what I refer to as 'supernatural phenomena' which are real effects with real causes.

No more than a river can communicate with people due to their proximity to it. If you are looking for water and you are close enough, the river will tell you that it is there.
I am saying that in the same way that a river provides information to the ears, 'auras' constitute a data source for the brain. My thinking is that electromagnetic energy can cause the aura to become distorted, lines of force being stretched and compressed in sympathy with an external field. I can envision how currents could be induced in the brain that interferes with ion movement and that the brain may be able to detect those changes and initiate a response that removes you from dangers posed by earthquakes or electrical storms etc. A little fine tuning by natural selection and to a certain extent, we read minds.

I think a more likely explanation would be the fact that women posses two copies of the X chromosome per cell whereas men only have one. Women can use the second X chromosome to compensate for any poor genes on the first. Whereas men cannot. This is why colour blindness is more prevalent in heterozygous XY men.

I don't know if it's really true but I do know that women necessarily have a different world-view to men. Men only have to contend with each other whereas women have to contend with each other but in addition they have to contend with men too. For reasons of survival, women had to learn about men, they had to cross a mental bridge that men don't have. It would seem natural to me that the ability to empathise is the result of selection pressures between the sexes.
Of course, intuitiion is a tool that benefits a man too but I think he gets it from his mother.
