That is actually a large amount of blood for a nosebleed.
then it will dry up in my nose and/or go down my throat
It drying in your nose is the point. It is called clotting, that is how bleeding stops. It going down your throat though isn't good, while not dangerous it can make your stomach very upset.
No thats a stupid idea, if you keep the blood in place it can dry and clot and stuff from what I remember
How is that a stupid idea? It drying and clotting is what stops the bleeding. Please do not comment medical advice on subjects you don't know about.
You filled up the entire sink? How are you still alive?
It looks like he filled the sink up with water and the blood diluted into it, making the water red. That isn't all blood. That's just unheard of.
You want a large bloodclot in your nose? I also took first aid for Boy Scouts
And I'm an EMT. Yes, that is what he wants. Their is a huge difference between a blood clot in an artery traveling to your heart, which is what I feel you are thinking of, and blood clotting to stop a wound from bleeding. Clotting is the bodies natural response to bleeding control.
It might be that cauterisation of the blood vessels near the surface inside your nose would prevent further bleeding.
This is good advice.
Basically, it could just be from low humidity drying out your nose making it more prone to bleeding. Or, as sir dooble said, you may have a large blood vessel which may need attention from a doctor. They will cauterize it and that should help to prevent further bleeds such as this.
