that just looks like normal blood pooling post death, just more purple than the usual pink which is because....? if you guessed hypoxia induced by consuming the SN causing red blood cells to not oxygenate the body, congrats you get an internet point
!
but seriously. google "livor mortis". this is a (mostly) normal part of the natural death process. blood pools and sinks in the body post death, especially when a corpse has not been moved.
I understand that seeing dead bodies is typically considered "weird" and "creepy" and knowing a lot about what happens to your body post death is not typical, but looking at those images, I see basically nothing out of place, barring the one photo where that person bit their lips frequently enough to leave scabbing. that wasn't due to the SN though, the scabs are too nice and even, very solidly built, so not something caused in the process of dying.
there's no need to fearmonger in a situation where you just don't know enough about the process. I'm not a forensics expert or a M.E. by any means, but I have spent a lot of time studying death and decomp because i too used to be terrified by death and decay. now I'm less scared because I'm informed. tbh if you're gonna try and freak people out with anything about corpses, it should be about how some flies just
know within seconds when something dies, and fly to the corpse
edit: forgot about the kidney and lungs (I think?) photos, and I'm not gonna speak on those because I know less about internal major organs. they could be weird, but tbh, I wouldn't be able to tell you what's weirdness due to SN or due to a medical malady.
