Report on Latent Narcotic Substances in the Brain: Drugless(1991)

A fake documentary disguised as an undercover report on a secret circle that teaches how to freely secrete the brain drug endorphins. At the end of the film, the director (Yoshihiro Kato), who has become a cripple as a result of his undercover work, reconstructs the images in his brain that he sees, and fantastic abstract experimental film-like images appear. It also contained elements of the video drugs that were popular at the time.
