==The cigarette story is weak== 
 "When two individuals are both delirious they may play off each other's imaginings. A subject was once to mumble,"Gotta cigarette?" and when his companion held out an invisible pack, he followed with,"S'okay, don't wanna take your last one." Incapacitng Agents, James s. Ketchum M.D.; and FrederickR. Sidell, M.D.  
 That's not good enough for me. There has been a verbal suggestion. No interrogation. Color of pack? Brand name? No controls. Do they really see the same thing? Doesn't any one wonder? You win some, you loose some. Thought you might find this amusing. As far as I have explored it, with invisible imaginary playmates, no one as ever asked," Do they really see the same thing?" Why not? Expecting more information.
