Can you guess what the question was?

Two brothers were watching a horror film on video late one night. One brother dozed off and dreamed that he was being chased by the crazy man from the movie, who was trying to kill him. In the dream, he hid in a cupboard. There was no sound except his heart pounding, and he had no idea where his crazed captor was. He was terrified!

The shock at that tense moment was enough that the sleeping brother suffered a massive heart attack and died instantly. True or false?
