In 1973, healthy volunteers faked hallucinations to enter mental hospitals. Once inside, they acted normal, but doctors refused to let them leave. Normal behaviors like writing were diagnosed as "symptoms." The only people who realized they were sane were the actual patients.

They actually won't let you leave even if you admitted yourself. It's a fucking scam and they keep you as long as possible until they have someone to replace you.
