I could probably explain the bloody nose if it was warm and dry in my house, but I don’t have the heater on. When I was a kid and had the nose bleeds, doctors told me that I had blood vessels very near the surface so a hard sneeze, or blowing of my nose could cause the bleeding. But as I got older I never had that problem again. Or at least if I did, it was very rare. I hope this isn’t a sign of something bad.
