I got bored and decided to make a thread based on unexplained phenomenons. Now I personally don't believe in paranormal beings, but I find the stories interesting and fun to talk about. So anyway, let's start off with a "paranormal-off."
1) Indrid Cold
Something that has been claimed as an extraterrestrial is Indrid Cold, more commonly known as the Grinning Man. Indrid Cold has had numerous sightings, one of which where he contacted someone through a telephone, and warned him about events before they happened. He is associated with the Moth-Man, and is said to appear in people's dreams. He has always been described as a tall, thin man without much facial features, beady eyes set far apart, combed-back hair and a grin stretching from one end of his face to the other. Before most people see him, they describe a small, floating object that makes no noise with flashing lights - much similar to a UFO. He has been spotted in West Virginia many times, and is also said to have a partner in crime named Apol on several occasions. People have reported him chasing civilians down streets, and asking for objects such as a ball-point pen or change, and becoming quite happy after receiving something so small. Cold is also said to have stolen some people's e-mail and phone-line to call others before calling the rightful owner of the e-mail or phone-line.
2) Slender Man
Originally claimed to be created on the Something Awful forums, Slender Man seems to have taken a life of its own. Not much sooner after its creation were there said to be sightings. Ancient Egyptian hieroglyphs seemed to depict the Slender Man, striking people's curiosity. Not much is known about the Slender Man's origins, but his objective is quite clear: to stalk and take actions against children. He is described much like Indrid Cold - tall and slim with a black suit, black pants, and a tie. The Slender Man has no facial features whatsoever, and his skin looks as if it is made of cloth. He can manipulate his shape and grow extra limbs from the back of his body which he uses to either walk or supress prey with. When the Slender Man holds out his arms, whoever sees him will be in a hypnotic state and be forced to walk toward him. He prefers foggy places and settings with trees. It is said that there will be sightings of him before children are to disappear, and that he is able to camouflage with trees. It is also said that everyone has seen him at least once as a child, usually in an accident. If the Slender Man fails to retrieve his prey the first time, he will be back when the child has turned into an adult. Another common saying is that anyone who sees him will become a potential target.
