This is excellent.

The great Brian Massumi writes about the Ganzfeld experiments of 1920s -1960s in the essay "Chaos in the 'Total Field' of Vision" (in Parables for the Virtual)

These experiments were supposed to expose the "pure" or "total" visual spectrum, but produced an absence of seeing and hallucinations, "Pure vision, the simplest fullest empirical conditions of vision, is visual chaos."

I think there is a useful parallel to be found in sound and noise. The larger point being that all perception (sight, sound) can not be strictly distinguished from hallucination.
