Not normal: Waking up with blood on your pants can come from multiple causes -- from menstrual period starting in your sleep to many others. If you're bulimic and throwing up blood, yes the blood you found could come from that. In this case you need to see a doctor asap, since you could have injured yourself. If you're not on your period, you still need to learn where the blood came from.
