The Buddhist symbol Indra's Net describes the world as a web spun by the cunning maker god Indra. The web is infinite. At every knot in the web a reflective jewel is hung. Everything that has ever existed, every idea past or future, every bit of data, is a jewel.

Every jewel is tied to every other jewel and every jewel reflects every other jewel. And so on ad infinitum. 

When any mirrored jewel is changed, all the other mirrored jewels are affected, inferring the notion of a non-self non-localized innate collective wisdom.

 SimStim is simulated stimulation, a passive viewing of the world through another person’s senses: their eyes, ears, nose, skin.

 In contrast, Virtual Reality is a simulated cyberspace experience for the mind only. VR worlds are simulations in which participants can live lives that would be impossible or dangerous in the physical world. The first great public VR hype occurred in 1992,when Jaron Lanier’s experimental work with VR gloves and helmets became public. The reactionary film Lawnmower Man captured the fascination and fear around VR.

Ironic use of memory lane, as Case's phenomenological primacy of perception is overridden by Molly's.

Does consciousness have a spatial location?

 René Descartes viewed consciousness as an immaterial soul which interacts with the body -- the object body is separate from the master subject mind.

Maurice Merleau-Ponty proposes that the body is forefront as perceiver of the environment and is both subject/object.
