Quietest room on Earth

too quiet.

It's said that you can hear your organs move.

but none of that is true

veritaserum stayed in there for almost an hour (?) and he came out just fine. I think he did say that he became more aware of his bodily functions.

Exactly, no hallucination, didn't turn crazy

A room as quiet as -9db causes hallucinations as you can hear things the human ear usually can't, and since your brain knows it's not in the room it begins to create imagery. it becomes so drastic that it can cause insanity and mental breakdowns.

Do you believe anything you read on the internet?
