Several years ago when I was about 10 years old (c.1976) I was watching the film When Dinosaurs Ruled the Earth, alone, when during one particularly violent fight between a T-Rex and Triceratops, my nose suddenly began to bleed quite badly. Several years later, I was watching the same film with my father, and when we got to the exact same dinosaur fight scene, I proceeded to tell my father what had happened the last time I watched the scene. He looked over to me and said "What? Like its' bleeding now?" My nose had once again spontaneously and badly bled.
