Virtual Hallucinations is an earphone-and-goggle training device for cops, paramedics and social workers which builds empathy with the mentally ill by putting them through the same experiences. It pretty much does what it says: simulates either schizophrenia or a really bad acid trip.
The first scenario puts you on a bus being attacked by predatory birds where people disappear and reappear, all while voices sinisterly tell you "He's taking you to the FBI!" Scenario two plants you at a pharmacy where the pharmacist hands you poison instead of meds, while people glare at you. (Kinda reminds me of Duane Reade.)
