I didn't know that not everyone could see what they were visualizing in their mind's eye. Is this a gift of some sort? I feel weird now. No actually I've always felt different. I have actually had dreams that have come true. Most of them are usually not good. My Mother and Grandmother(RIP) are the same way. It almost sounds like it's a gift of genetics or something.

Can anyone recommend any good books on clairvoyance?

I just started reading Energy Work, and I have to say that I love it as much as I liked Astral Dynamics, because it explains things that have happened to me that I may not have learned about otherwise. For example, natural clairvoyance in "Energy Work", and the dweller on the threshold in "Astral Dynamics." I hate the dweller. First time that I saw him, it scared me because I thought someone was in my apartment. The second time that I saw him, it was as if he wanted to do damage to me for some reason or another. Oh well, he'll get his in the end.
