Phil Dick and I had a long conversation one afternoon at Santa Rosa, and it was only a year later that I found out that he and I had exactly similar experiences at approximately the same time, which left both of us wondering if we'd been contacted by god, by the devil, by an extra-terrestrial from Sirius or by some evil parapsychologist working for either the CIA or the KGB, or if we had just gone temporarily crazy. Then I realized this whole long conversation was Phil's attempt to find out how crazy I was. If I was sane, there was a chance that he was sane too. But if I was crazy, that increased the probability that he was crazy. He apparently decided that I was sane enough that could trust that he was possibly sane took, so he started publishing some of his experiences, which now are in several books: Valis, The Divine Invasion, The Transmigration of Timothy Archer, Radio Free Albemuth and the Exegesis. My accounts of similar experiences are in Cosmic Trigger Vol. 1."
