Reminds me of the following joke.
A man goes to a psychiatrist who asks him what his problem is. The man announces that he is dead. The psychiatrist works with him for 6 months trying to convince him that he is alive. But nothing works and the frustrated psychiatrist tries one last intervention.
He gives the patient a book entitled "Blood and the Circulatory System". He tells him to read chapter 19 "What happens to the blood after death?" five times and report back next week.
When the patient returns the doctor asks him if dead people can bleed. "Of course not the patient says, once the blood coagulates it is impossible." Great says the doctor as he jumps up from behind his desk and stabs a needle into the patients hand. As blood spurts out, the patient stares incredulously at his hand and says,
"Doctor....dead people do bleed after all!"
