Yes. YES. I get them all the time, more so during the summer. They tend to happen at the worst moments, too. For example, once, I was talking to my cousin about something. She was on the computer, and she was looking around for a manga to read. I felt the nosebleed coming, and at that moment, I turned to look at her screen -- there was a very revealing picture of a lady there. The nosebleed came at that moment, and it was also at that moment that my other male cousins came in the room and saw me have a nosebleed after looking at what what on the computer screen. Being a girl myself, this gave them the completely wrong idea.
I also get nosebleeds during school quite often. Particularly during science classes, though that's probably a coincidence. It's pretty annoying when you bleed all over your classwork, though.
