my good friend experienced cocaine psychosis,after isolating in his apartment for six days straight(very little sleep-6 hrs. in total) he had vivid hallucinations while he was talking to me: cameras, twenty or so detectives tapping into his computer,"playing the frusration game"to allure him into confrontation,feeling trapped in his apartment,having no control and feeling powerless to his hallucinations..I eventually had to call the ambulance,as he broke down in tears..He broke free from his captives (in his mind)and called me on the sixth day..He was alone with his pyschosis for the five and a half days prior.
