Josh P. Warren was on C2C recently taking about how to "make a ghost or apparition" it's been done before and evidently many times. I read a book about this several years ago, it seems an American woman had heard of a puka and she wanted to try making one. She went to Nepal or Tibet and got 4 or 5 people who knew how to do this to help her. All decided what the person they wanted to exist would look like, his likes and dislike, etc..It took some time before a misty, human looking form began appearing, as time went on it became more solid, then it became like a real, live, breathing human. Quite friendly, a joy to be around, as time went on it because selfish, developed a mean streak. It was time it had to go ! Getting rid of it was much more difficult than making it. The elders told her if all the "makers" died while it was still here it would remain forever. They finally did manage to undo it and said never again. It was to real, to human and they were forced to kill it to undo the damage they had caused by bringing it into existance.
