No one has really seen a man become a wolf. People with long hair and fangs at full moon certainly don't exist. But some diseases, such as hirsutism and porphyria, can make patients look terrible. Porphyria patients' teeth and nails will turn red, and these unfortunate patients are also very afraid of sunlight, which is completely in line with the legendary werewolf, because it is said that werewolves only move at night. Sunlight can make porphyria patients itch all over the body, appear erythema on the skin, and sometimes even grow body hair. At that time, the image of porphyria patient was a werewolf who had not fully recovered his human form.
There is another possibility: "werewolves" are victims of mental illness ... Of course, patients will not really become wolves, but they will feel that they have become wolves. This situation is extremely rare, and patients will fantasize that they have become wolves, which is very aggressive. Go out only in the middle of the night, eat only raw meat, and eat all the killed animals! Now, patients can recover their mental health through medication. But if the same thing happened in the Middle Ages, what would happen to such unfortunate people?
Zombie poison
Real zombies have nothing to do with what you see in horror movies. In the Caribbean island country of Haiti, voodoo introduced with African slaves has been popular for nearly five centuries. Zombies are inseparable from this religion. In Haiti, the popular saying is that zombies are men and women who have been identified as dead, but suddenly returned to the living world. In fact, these people are not really dead. They are just victims of voodoo wizards. Legend has it that these zombies are "remotely controlled" by wizards and become free labor. It is said that these zombies used to work hard in the plantation.
Wade Davis, an American scholar, believes that all this is related to the mysterious powder used by wizards. By analyzing the composition of the powder, Davis finally found a toxin extracted from the liver of puffer fish: tetrodotoxin. This toxin can put the victim into a coma, slow down the physical activity, make the heart beat abnormally slow, and lead people to mistakenly think that the victim is dead. But when the toxicity of tetrodotoxin passes, the victim will wake up. However, due to lack of oxygen when buried underground, the victim's brain was damaged. When he wakes up, his steps are stiff and his eyes are frightened. People will think that he is a resurrected "zombie".
Cyclops? Who are you kidding?
Homer, an ancient Greek poet
In the epic Odyssey, the cyclops Polyphemus lived on an unknown island. This is fiction, right? If you ask the ancient Greeks like this, they won't understand why you have such questions. These ancient navigators were convinced of the existence of this monster, because when they sailed between the islands in the Mediterranean, they did find some skulls, and these skulls really only had a huge eye socket. In the Middle Ages, other skull fossils were found in Palermo, Sicily. It is said that the poet Boccaccio exclaimed after learning the news: "We have found the bones of Polyphemus!" But today, we all know that cyclops is just a mythical creature. In fact, these skulls belong to prehistoric pygmy elephants. The hole in the upper part of the skull is actually not where the cyclops' eyes are, but the nostrils of the dwarf elephant.
