What did you encounter in college?

when I was an undergraduate, I once slept in the middle of the night and felt my nose was wet. I thought I had a runny nose. When I rubbed it with my hand, it smelled of blood. Then I knew I had a nosebleed and I was awake. I touched the pillow, and it was wet, and my face was covered with blood. I knew it was a little serious, because I had a nosebleed before, and my nose bled and my mouth vomited blood. Then I got up quickly and stuffed my nostrils with toilet paper. Sure enough, blood flowed into my mouth and I vomited a few times, but I still couldn't stop it. I'm a little panicked. I have to go to the school hospital to see it. So I shook my roommate in the next bed, and she was sleeping soundly. I said, "Dan, wake up quickly. Don't be afraid if I tell you something." She whined about whether she would wake up or not. I said, "I have a nosebleed. I can't stop it. Now I look bloody. Get up quickly and accompany me to the school hospital." She bounced out of bed … I can't imagine what it's like for a sleeping person to be awakened by a man with blood all over his face at three o'clock in the middle of the night.
