Hallucinations are caused by sensory-deprivation rather than motor parylization. For example, float tanks, also there are specially designed rooms that have as close to no background noise as possible, and people report hearing all kind of audio hallucinations such as bees, etc.
This test demonstrates he can at least hear sound. I'd imagine the effects would resemble senility from lack of engagement more.
Over stimulation by excitatory neurotransmitters is the primary cause of neuron death during stroke, the idea is that many neurons thought to be dead might have just shutdown to prevent from being overstimulated. And if baseline stimulation is reduced enough through what is normally sleeping medication, they might actually start to activate again.
I'm not sure that I meant hallucination in the clinical sense. I meant that if I was trapped inside my own mind for months on end, I would have nothing else to do besides create elaborate fantasy worlds in my mind and I suspect many others would do something similar.

Also, interesting side note, sleeping drugs such as Ambien in some cases allowed patients in coma to regain awareness and even hold CONVERSATION: http://www.guardian.co.uk/science/2006/sep/12/health.healtha...
