Does anybody know of the psychotherapist in question Rud Grandt, or have any information on cases like his.
Here is what the authoritative
Handbook of Hypnotic Suggestions and Metaphors edited by D. Corydon Hammond Ph.D., An American Society of Clinical Hypnosis Book, 1990; says about past-life Regression on pages 511 to 512:
PAST AND FUTURE LIVES
When the technique of age regression is discussed, questions about the possibility of regression to past life experiences are often raised. This controversy stemmed in large part from the famous Bridey Murphey case (Bernstein, 1956), in which a lay hypnotist hypnotized a woman who subsequently imagined herself to be the reincarnation of an Irish woman. Credible hypnosis experts immediately debunked the idea (Kline, 1956), and in fact investigative reporters discovered background experiences of the woman that accounted for her seemingly inexplicable knowledge about Ireland (Gardner, 1957).
The phenomenon of source amnesia (Evans & Thorn, 1966) thus seems adequate to account for this and the many similar cases (Barker, 1979; Edwards, 1987a, 1987b; Harris, 1986; Wilson, 1982), where investigations have both revealed flaws in the accounts of the subjects and have also identified that they had been exposed to historical information in the past that was related to their presumed past lives. In cases that have been investigated where the regressed subject supposedly spoke in another language, a linguist found the claims to be patently false (Thomason, 1984, 1986-87). Carefully controlled research (Baker, 1982) has also confirmed that having the experience of regressing to a "past life" is based on a combination of the expectations of the subject and of suggestions and the demand characteristics from the hypnotherapist. But, despite scientific evidence to the contrary, there has never been a dearth of gullible individuals willing to believe in anything from abductions by UFOs to people living inside the earth under the north pole (Hines, 1988). Thus, there continue to be individuals who will promulgate a belief in regression to previous lives, most of them lay hypnotists.
However, there are also skilled and respected professionals like Barnett (1981) and Cheek (Rossi & Cheek, 1988) who believe that it is possible to regress patients to birth experiences and even prebirth uterine experiences. Despite fascinating recent evidence about the ability of the fetus to hear, which may give one pause to wonder, regressions to uterine or birth experiences seem to me more likely to consist of projective processes. However, if a patient should spontaneously "regress" to such an experience, it may still be useful in promoting therapeutic change. From my point of view, such "believed-in imagining" may, because it is believed by such a patient, be a catalyst for altering perceptions and at the same time provide a face-saving excuse that some patients need.
