According to Osho, past lives are not fiction but a lived reality once directly experienced; until then they seem like stories. He says he remembers his own past lives, and that in deep, relaxed meditation the unconscious reveals these memories like a movie. The test: true recollections repeat consistently, unlike dreams which shift; repeated sameness indicates genuine memory, not fantasy.
They seem made-up until you directly see them; get very quiet, and if the same old story appears again and again, it’s memory, not a dream.
