Hi, I have a close friend of mine (23 years old) who suffered from a sudden, unexpected death. He bloated in just a short period of time, and mouth foaming was observed (which is a big question on the probable cause). Half of his body (upper part) was in black-like appearance, and based on doctor's initial statement, this might be due to the blood vessel rupture.
Few questions arise:
What caused the occurence of mouth foaming?
Is it normal to be bloated once dead?
Is it cardiac-related factor as the person previously mentioned heart-ache?
Some persons said it's a nightmare, how true is this attribute?
