my dad was in recovery after his triple bypass & heart valve replacement at age 88. he read a robin cook novel about organ thieves and thot he was living it. he chewed thru the wires attached to him and was tryin to open his window to jump. a nurse came in and tied him down. he came out of it and remembers everything. it is now 7 wks later and he is still ok except for becoming easily frustrated and cranky. havin family with him helped, as the hallucinations quickly changed to harmless ones and stopped a couple wks later.
