Not sure what this tulpa stuff is about... haven't read it all as yet but it does remind me a little of the Canadian 1972 Phillip Experiment.... In the late 1990s I belonged to a local Paranormal group and for a number of months a number of us would meet privately away from the group every week to try to create an entity based on the Phillip Experiment...
I have long forgotten how successful we were or weren't, but I do remember at home sometimes the other people living at my place used to say things like... 'get your ghost creation out of here', 'tell your ghost to leave' or 'you and your ghost'...
"The Philip Experiment was an actual historic research project conducted by a Toronto organization in 1972 in an effort to prove that paranormal entities such as demons, spirits, ghost, and poltergeists were manifestations produced by human will through expectation, imagination, and visualization. A prominent group of citizens, three men and five women with no interest in the occult, participated in the study, the results of which not only shocked the group but stunned the world. The how and why of The Philip Experiment has never been answered leaving many to wonder – did the group accidentally summon a demonic or spiritual entity or did they create a real ghost?"
