Ah, yes, the confirmed skeptic. When I have been badgered into describing experiences I've had that can't (yet) be measured in a scientific sense, I've been asked to prove the reality of the experience to the skeptic. I've come up with a good response: "I don't feel any need to do so. I don't care if you believe me or not." They usually laugh and move on. The fact is, I don't even feel any need to prove it to myself. It doesn't really matter if the experience is "real" or just a artifact of brain chemistry. If it has an effect on my perceptions and understanding, it has it's own reality. Besides, artifacts of brain chemistry are real . . . .
