Is it really possible for people to actually sweat blood if they're really, really scared?
nah
Actually; yes, that is possible
jesus did it
I shit blood when I'm really scared.
only possible if you have damaged sweat glands
Only if they're a vampire.
It is possible, but it requires something REALLY FUCKING SCARY for a long time.The blood that comes out isn't same as vein blood. It's more vicious and dry because it is "filtered" through skin.
impossible bullshit
Actually it's proved possible.
