Nose bleed during a cold??

So I have a “cold” and I slept with the heat on last night , with vapor rub on my chest and under the covers to try and sweat the cold out. This morning when I first woke up, my nose had dry boogies in it and a lot too, so i started to blow it, thinking that it was snot coming out but it was a pool of blood. Think maybe I got overheated???
