HYPER REVERSION
Hyper reversion is a curse among animalia exclusively. It's spread from animal to animalia, and then between animalia as well. It's extremely contagious, and patients with this curse need to be put into a sealed off area.
The curse lays dormant at first, but after a while the cursed individual can get thrown into hyper reversion shock at any moment. This attack causes the body to release all adrenaline it can muster, the individual gets thrown into a state of shock, confusion and pure fear. They lose all comprehension and logical thinking, whenever this state kicks in it's a life or death situation. They will not remember what happened during the attack, and even if a situation where the hyper reversion is triggered isn't threatening, the individual would still see it as a dangerous situation. Often the individual would try to run away from everything around them, and occasionally engage with others by hitting them, pushing them away or attacking them out of defense.
The most dangerous part of this curse is the damage the stress does to the heart and brain, the next most dangerous part is how the cursed individual is extremely unpredictable under a hyper reversion shock. There has been cases of individuals accidentally hurting or killing themselves when trying to flee from a situation, or engage with it. Then the third most dangerous part is how this can affect the people around them. There has been many documented cases or cursed individuals harming the people around them without really wanting to.
People who feels guilty, tormented and overall ashamed are more susceptible towards this curse. As curses are sort of like "magical sickness" it can sometimes avoid particular individuals, while flocking and storming around others.
Some say this curse is linked with werewolves.
