The Galactic Question Center

I'm not sure what it tells us of the nature of reality other than it could be subjective at best and tenuous at worse (or tenuous at best and subjective at worse depending on your attitude).

I suppose that if you looked at these instances with a "brain as reality filter" or "brain as transceiver" then perhaps the lack of the, arguably, primary sensory input for humans could cause sections of the brain to become more attuned to the galactic carrier wave.

On the other hand, though, the same deprivation could cause a bit of neurological malaise. Sight(not necessarily vision, semantically speaking) is based, largely, on one's brain filling in the blanks.
 

Weren't most of the patients already blind or diagnosed with some profound vision impediment, bigbody?

But that was a pretty snappy answer. Well played.
 

When I was a teenager, a friend & I were driving back home at night from partying in Mexico. I was rudely awakened by him slamming on the brakes & skidding to a stop in the middle of the highway. Upon asking what was wrong, he told me there was a yacht laying across the hi-way. At which point I drove the rest of the way home.
The moral to the story is things you put in your body, even alchohol, can make a person see alternate realities. The yacht wasn't a reality, but it was to him. Phisical & mental diseases can do the same thing.
I love to think about alternate realities & other dimensions, but when it comes to drugs & diseases I tend to think the duck is a duck.
