JMitch,
But how do you know that your experiences were not an artifact of your mind (like the delusions of a schizophrenic might be)? That's why we need a measurement, a recording of these purported "events" through the sorts of instruments that simply cannot fabricate data, or falsely associate it with some memories or mental images.
For example, if people really are abducted by UFO's, I want a digital recording of the visit, a material proof that the person was actually gone from their bed and indeed from their building, through no doing of their own, I want a UFO to crash into a bird and send it down with broken bones, I want a remote viewer to correctly and completely describe the colors of all the chemicals present on Titan's surface before such measurements are carried out scientifically. There actually is a million-dollar prize out there for indisputable proof of a psychic phenomenon. Years later, the prize remains unclaimed.
If Poltergeists really can throw things around, I want an actual recording of the event. If ghosts can be seen by our eyes, then they can be seen by our cameras. But what makes me most suspicious is the claims of the NDE people. They claim to have "seen" things and "heard" things -- but obviously not through their real eyes and ears, which were resting together with their body in a hospital or wherever. Yet, the experience of seeing and hearing is intimately connected to activity in the corresponding visual and auditory corteci. For example, applying mild electric stimulation to these areas of the brain during open-brain surgery evokes sounds and images in the patients' mind. The acts of perception and memorization inherently speak of physical phenomenology within the networks of the brain. Such are the acts of the body, not the (inexistent) soul.
