I was recently reading a creepypasta about how a man's nerves were cut so that he could not experience any of the senses in order to make contact with God.

I do not care about the theological aspect of this story, but is it even possible for a person to survive with none of their senses? If so, how would they perceive anything? Would they go insane?
