A lot of things: First, it would help to know where the blood is coming from. Do you have bleeding gums? Do you have nose bleeds? Do you have any symptoms of a stomach ulcer or reflux? If you're having bleeding gums or nose bleeds in your sleep, you could have a condition causing your blood to not clot properly. There are numerous causes of this and you should see your doctor and have this investigated further.

If it is not nose bleeds or the gums and you have a significant amount of blood in your mouth the list of possibilities is quite long and has some very minor to much more serious issues and should be checked as soon as possible.

Many: It could be bleeding from your gum (infection, inflammation), teeth, nose bleed (nose and mouth are connected). If it occur in more than one occasion, you should see doctor to exclude benign bleeding disorders such as low platelets.
