This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

A description of the experience

Into the Light – Fay Marvin Clark

I was very impressed by one series of experiments conducted with high-frequency sound produced by an audio-generator. A teacher, William Petersen, conducted the tests which were given for periods of two minutes, each one using a different frequency. The purpose was to determine the effect of high frequency sound on the endocrine centres, or psychic centres, of the body, as they are sometimes called. Some of these tests affected me very strongly in certain areas of my body, and I decided to continue the experiments myself at the earliest opportunity.

Of these psychic centers, which we are told are seven in number, the adrenals, the thymus, the thyroid, the pineal, and the pituitary were of the greatest interest to me, as the areas where some of those glands are located seemed to be the most affected by the sound experiments. Experiments were also conducted using colour to show that certain colours tend to produce the same stimulation experienced by the corresponding sound vibrations (Sound and colour both being based on rates of vibration or frequency).

Soon after our return home, we purchased an audio-generator kit, unassembled, and it would have no doubt remained unassembled if it were not for the kind assistance of two Collins Radio Company engineers who were also interested in the "Chakra", or psychic centers as we called them.

During the next few years my wife and I, together with our engineer friends, spent many hours experimenting with the various frequencies and numerous light combinations.

I am convinced that one can stimulate these psychic centers and promote their sensitivity. We certainly were able to move into altered states of consciousness as a result of using certain frequencies. The state of consciousness also changed when certain lights were used in combination with the high frequency sound signals. I am sure that this is a field of research that requires one to have a very well-balanced mind. I believe that there may be a danger in using certain frequencies, but again, what might be damaging to one might be beneficial to another, as we found that apparently no two persons responded exactly alike to the same rate of vibrations.

At that time I was not interested in physical phenomena; but I was convinced that certain frequencies could cause weightlessness, if not actual levitation. Sometime in the near future I hope to find the time and solitude to continue my experiments with sound and colour.
