I've heard of an actor who got so into role-playing, he forgot he was an actor playing a role. He was meant to slay dragons, but terribly afraid of getting eaten in the process. It kept him up at night, he asked people how to cope with the stress and got plenty of advice, to which he replied the suggestions don't address his actual problem.
