Both the song and the video seem to be from the perspective of a person with a disease or disability which causes seizures or involuntary movements, but also provokes visions. As is sometimes the case with tumors or damage in some parts of the brain, the visions can be unimaginably beautiful, almost impossible to return to "reality" from -- but they're also part of a disease which may be killing the body. "Curing" the disease might be the only way to survive, but it would mean losing the purest expression of beauty and transcendent meaning that a person might ever be able to experience.
