Your body bleeding internally (i.e. inside of it). If it is severe enough it can lead to damage all over the body. Can be caused by internal injuries (for example, a glass shard lodged in your lung, which would also cause a collapsed lung) or pathogens in the hemorrhagic fever category (ebola, dengue and yellow fever for example) which cause your body to have clotting problems. If you think you're internally bleeding, get to the hospital ASAP.

Friend of Person: We'll send you to the hospital real quick! Internal bleeding is extremely dangerous!

The Sentinelese is the tribe of North Sentinel Island. They are the last hunter-gatherer tribe in history and will lash out and attack outsiders. Basically, you shouldn't mess with them.
