Carderro, Mr.Sprinkles, I agree with you both. All I've maintained is that scientific experiments could be devised to test such claims about out-of-body experiences, past lives, and telepathy. Even if confirmed, there would still be a question of whether "spirits" or mental phenomenon were at work. Obviously, in the past life/ language thing, gibberish would not satisfy. Ideally, there would be a person who can converse in the old language sitting in on the hypnosis session, talking to the "regessed" one, and the whole thing videotaped.
The dog telepathy thing may seem odd to you. The described phenomenon is a dog who goes to the front door, turns circles, scratches, whines (as if someone were there), when her master leaves work to come home from a job 30 miles away. Other dogs have been noted to respond to command from masters out of sight and hearing. These things would be easy to confirm with two fixed camera which record time and date. This method would also test human twins, and mothers and children, who report picking up the telephone to call the other only to find the other already on the line (before the phone rings).
