Bob Haskins (Roger Rabbit): Unwitting Magician

As a refresher here is an exerpt from the Wiki on Tulpas: Evans-Wentz (1954: p.29) discusses tulku (or nirmanakaya) and tulpa:

Inasmuch as the mind creates the world of appearances, it can create any particular object desired. The process consists of giving palpable being to a visualization, in very much the same manner as an architect gives concrete expression in three dimensions to his abstract concepts after first having given them expression in the two-dimensions of his blue-print. The Tibetans call the One Mind's concretized visualization the Khorva (Hkhorva), equivalent to the Sanskrit Sangsara; that of an incarnate deity, like the Dalai or Tashi Lama, they call a Tul-ku (Sprul-sku), and that of a magician a Tul-pa (Sprul-pa), meaning a magically produced illusion or creation. A master of yoga can dissolve a Tul-pa as readily as he can create it; and his own illusory human body, or Tul-ku, he can likewise dissolve, and thus outwit Death. Sometimes, by means of this magic, one human form can be amalgamated with another, as in the instance of the wife of Marpa, guru of Milarepa, who ended her life by incorporating herself in the body of Marpa."

Bob Haskins inadvertently creates a Roger Rabbit Tulpa:

"And then I watched my daughter, Rosa, she was three at the time, and she has all these invisible friends whom she talks to - Geoffrey and Elliott. And I realized that, as we get older, our imagination goes further and further to the back of our head. When we're a kid, we can actually take it out and look at it. I mean, we can see it. As we get older [still], senility comes in, and the imagination comes to the forefront again, and takes over.

"So, I just concentrated on an immature imagination - forcing it back to the front so I could actually take it out and look at it. And I managed to actually see them, which was all right, but you do it for 16 hours a day for five months... ! I started to lose control and hallucinate in all kinds of embarrassing places. Some of it's quite rude, but there's not much you can talk about. At one point, it was quite frightening, weasels and all sorts of things turning up."
