On August 23, 1971 the first of many images appeared on the kitchen floor of Maria Gomez Pereira's home in Belmez, Spain. This first image was of a man and was so disturbing in its grimacing appearance that it prompted Maria to have the cement floor torn out and replaced. A week later, the second of what would be many unique portraits made its ghostly impression on the floor, which the family also - understandably - wanted destroyed. Hearing about the faces, the Mayor of Belmez had part of the floor removed and saved to try to determine what was causing the ghostly faces.Under the slab, human remains from a medieval cemetery were found and properly reburied off the site, however two weeks later yet another face appeared on the new floor. More and more faces in increasingly elaborate arrangements came and went on the floor until the family finally sealed the kitchen, however this simply resulted in more faces appearing elsewhere in the house. By now well publicized and attracting the attention of investigators, the phenomena was intensively studied, including the placement of microphones which reportedly picked up sounds inaudible to the human ear that seemed to be muttering strange languages and agonizing moans seemingly choreographed to the grimaces and painful contortions of the faces on the kitchen floor.

Maria died in 2004, however the faces have continued, calling into question theories that the old woman had been faking the whole affair. Further, chemical studies of the cement have been somewhat unsatisfying, with multiple potential explanations being advanced, from acids to paint but none of them really seem to cover all aspects of the phenomena.The annals of the paranormal are replete with images of people on inanimate objects. From Christ himself to Mary on a grilled cheese sandwich, we recognize faces in patterns and often attribute these images to a wide variety of people. Most of these can easily be explained by wishful thinking and recognizing patterns among the chaos, but sometimes a story can be attached to the phenomena that might suggest that the spirit of a disembodied human may be able to manifest a picture of themselves that the living can see.

I've looked into this for sometime now. Here we have a classic example of paranormal staring scientists in the face, in which they cannot answer. Instead they shrug and move on, denouncing that spirits and such paranormal events are simply not possible.

Nobody ever disputed the fact that there are some brownish spots that look like faces in that house. All the scientist who actually seen them ever stated is that they could not, at that point, explain these faces. Paranormal investigators have not given a satisfactory answer either.

Oh those faces are really cool. Definitely creepy too.

Do you agree with that?
But have a look at this. This is definitely a human face. It will never be brought about by simple wishful thinking!
