My version is Greg is an addict. Addicted to painkillers at first . I noticed in the beginning , semi subliminal signs for Safe Harbor rehab . When his female companion and he gets their fix , they are in a pretty magnificent world ( bliss) . As they comes down , between hits, he and his female companion start to reenter reality . They get hooked back up and head back into the perfect world . Greg’s daughter tries to help him back to reality . His son seemed to be apathetic. I thought it to be a thought provoking real look at drug addiction.
