In fact there are plenty of cases where people were conscious after being declared clinically dead (brain death being one of the criteria), Commonly shown by being able to describe events that took place in an emergency / operating room during the period in which they were clinically dead.

You really do talk right out of your ass. don't you?!? No one recovers from brain death you moron.

Brain death.

"Brain death is loss of function of the entire cerebrum and brain stem, resulting in coma, no spontaneous respiration, and loss of all brain stem reflexes. Spinal reflexes, including deep tendon, plantar flexion, and withdrawal reflexes, may remain. Recovery does not occur."

Brain death is permanent and irreversible Huggies. Of course, if you ever actually read up on what you claim you'd know that.
