This is one that the sceptics rarely mention, presumably because it upsets their worldview. Creation of thought forms, such as the one described below, is fundamental to magic. Notice also how they gave life to their creation by surrounding themselves with associated objects and performing relevant actions, which is another classic principle of magic, namely like attracts like, and to which rituals are geared.

+++The TSPR, under the guidance of Dr. A.R.G. Owen, assembled a group of eight people culled from its membership, none of whom claimed to have any psychic gifts. The group, which became known as the Owen group, consisted of Dr. Owen’s wife, a woman who was the former chairperson of MENSA (an organization for high-IQ people), an industrial designer, an accountant, a housewife, a bookkeeper and a sociology student. A psychologist named Dr. Joel Whitton also attended many of the group’s sessions as an observer. The group’s first task was to create their fictional historical character. Together they wrote a short biography of the person they named Philip Aylesford.+++
+++In September 1972, the group began their “sittings” - informal gatherings in which they would discuss Philip and his life, meditate on him and try to visualize their “collective hallucination” in more detail. These sittings, conducted in a fully lit room, went on for about a year with no results. Some members of the group occasionally claimed they felt a presence in the room, but there was no result they could consider any kind of communication from Philip. So they changed their tactics. The group decided they might have better luck if they attempted to duplicate the atmosphere of a classic spiritualist séance. They dimmed the room’s lights, sat around a table, sang songs and surrounded themselves with pictures of the type of castle they imagined Philip would have lived in, as well as objects from that time period. It worked. During one evening’s séance, the group received its first communication from Philip in the form of a distinct rap on the table. Soon Philip was answering questions asked by the group - one rap for yes, two for no. They knew it was Philip because, well, they asked him. The sessions took off from there, producing a range of phenomena that could not be explained scientifically. Through the table-rapping communication, the group was able to learn finer details about Philip’s life. He even seemed to exhibit a personality, conveying his likes and dislikes, and his strong views on various subjects, made plain by the enthusiasm or hesitancy of his knockings. His “spirit” was also able to move the table, sliding it from side to side despite the fact that the floor was covered with thick carpeting. At times it would even “dance” on one leg.+++
+++The Philip experiment was so successful that the Toronto organization decided to try it again with a completely different group of people and a new fictional character. After just five weeks, the new group established “contact” with their new “ghost,” Lilith, a French Canadian spy. Other similar experiments conjured up such entities as Sebastian, a medieval alchemist and even Axel, a man from the future. All of them were completely fictional, yet all produced unexplained communication through their unique raps. Recently, a Sydney, Australia group attempted a similar test with “the Skippy Experiment.” The six participants created the story of Skippy Cartman, a 14-year-old Australian girl. The group reports that Skippy communicated with them through raps and scratching sounds.+++
