building. I could not make contact with the man, but the woman (no physical identification other than this) seemed to know I was there. I asked her if she knew who I was, but I could get nothing other than a sense of awareness on her part. The vibrations started to fade, so I backed away, dove into hole, rotated, and sat up. Total time of the entire episode was forty minutes. What can be made of these experiments? Taken at face value, they add up at the least to an unusual hallucination. At most, the observations show a developmental pattern. First, there seems to be nothing in written history of such experiences as these to offer a comparison. These were not spontaneous incidents, but deliberately planned and systematically repeated. As such, they would appear to be unique. Second, the experiment was repeatable by formula: (1) the setting up of the "vibration" condition; followed by (2) a 180° rotation; and (3) the appearance of the "hole." The experiment was performed not once but at least eleven times. The 180° rotation offers interesting speculation. The reference to "out of phase" and the apparent identical displacement in exact opposition deserves the attention of the physicist. Wave-form studies of phase relationships applied in this case might provide a fruitful theory. The blackness of the hole was evidently a matter of my own limitation in "seeing." Through the early experimentation, the restriction of vision was selfimposed, as I felt this was a requisite for maintaining the vibration condition. The evidence seems to point to this in the success in seeing when I decided or tried to see, and did. It would have been interesting indeed if I had utilized my vision during the long exploratory "flight." Much might have been learned. The experience of the "hands" defies explanation. There is no evidence to indicate that I was conditioned or suggested into the first discovery of the hand. Second and later such experiences, however, could well have been of this source. But this in no way invalidates the first of these impressions. The card with the address might fall into the classification of past memories, associated with the handshake of a first meeting. Unexplained still is the "digging" of the "hook" into my hand. The calling of one's name is not uncommon under other circumstances. There are numerous records of such sourceless voices, both in the waking
