I'm looking for the author and title of a story where a process is used to transform people into their alter egos. All I remember is a bag lady turned into a sort of Amazon warrior, and a rich gangster turned into a flying elf-like creature. Any help would be greatly appreciated. I think this story was written in either the 1970s or possibly the 1980s.
I found this story. It is called 'Jean Sandwich, the Sponsor, and I' by Ian Watson, and appeared in UNIVERSE 11 in 1981, edited by Terry Carr.
