'Quietest place on earth’ causes hallucinations

I have come across the following video and article by Nguyen today and had to re-blog it. It is difficult for me to even imagine how quiet this anechoic chamber in Orfield Laboratory really is. I wonder about the connection between such chamber and let's say being imprisoned in a solitary confinement. Prolonged exposure or stay in both conditions seems to have negative impact on a human being.

"While we all can appreciate getting some peace and quiet every now and then, you might be surprised to learn that there’s only so much of it the brain can take.
That’s what scientists have discovered based on the reported experiences of those who have spent some quality alone time in Orfield Laboratory’s anechoic chamber, a room that’s so soundproof, it’s officially listed as the “Quietest place on earth,” according to Guinness World Record."
