I posted earlier in this thread, and must confess, I haven't read all the responses here, though I see that it has gotten into a religious debate.
As I stated earlier, I think everyone has some degree of psychic ability, but either don't recognize it or don't choose to develop it. I think many people delude themselves about this, either by seeking readings and advice from a purported psychic or from developing it into some sort of trade for themselves.
I went to one "psyhcic reading" party at the invitation of my good friend who believes in it totally, with a noted local psychic. He talked a lot, and fast, when I entered the room with him. He is good at this, talking till he "hits" on something, and then goes from there. These people are skilled at what is called "cold readings."
I want to add here that I'm amazed at the number of TV shows about psychic detectives, and ghost hunters. I think any one of us could do that...enter a place and say we "sensed" something!
None of us can really know the depths of perception of the human mind. I do think there are things that cannot be explained. Even animals are psychic.
