What delusion did Roky Erickson reportedly hold around 1987 concerning his physical body?

Answer

A Martian had taken over his body

During the complex period following his institutionalization, Roky Erickson exhibited persistent delusional beliefs that were part of his public persona in the late 1980s and 1990s. Specifically, around 1987, he maintained the conviction that an extraterrestrial entity, a Martian, had successfully occupied and taken control of his physical form. To formalize this belief system, he even went so far as to have a lawyer draft and notarize a contract officially declaring him to be an Alien, illustrating the depth of these trauma-related or drug-induced manifestations that complicated his life outside the hospital.
