Who can tell if we are the natural entities? Maybe is like Matheson's "I'm a legend" novel, and we're nothing but the last ones of a race in a complete strange multiverse. According to our perception, we call supernatural, strange, metaphysical, preternatural or even unearthly all that things that we haven't know yet. I think every one of us has our own personal point of view about all this, and maybe it's our own anxiety the one that makes us perceive (or not) all this supernatural entities; people believes in what they want to believe, after all. It's not strange, then, that small children and some adults too can "see" or "feel" this entities all around us, because they can -in a way- put their anxiety away and "connect" to the other dimensions, else worlds or universes (call them as you want to). Sören Kierkegaard describes anxiety as a "vague and confused discomfort"; Rollo May talks about anxiety as a "perturbation without a name or a shape", and that's exactly what this people feel when they reach this entities, but most of us just don't know how to handle this feeling, and we loose all the chances to reach them too.
Anyway, I do believe and love all this crazy and wonderful things... Here in my country we grow up and live in the middle of hundreds of beautiful horror stories and legends (ghosts, demons, spirits, witches, vampires, and much more), so it's idiosyncratic to be part of a supernatural experience in different levels of participation.
Going to the supernatural experience, let me tell you that my working place is a beautiful huge house with more than 120 years old and located on a really old part of the city. It has three floors and a basement, with lots of small rooms that were used as hospital rooms or cells, with small windows on the doors or very heavy doors made of strong wood. Through history, this house has been a mental institution, a horse ranch, a prison during the revolution war and many other things. It's well known that there are a lot of supernatural presences in here (cacophonies, ghosts, etc.) but the famous ones are: a little girl who plays and runs on one of the halls of the first floor; the first owner of the house, who appears at the entrance door of the basements, dressing like a horse rider; the owner of the mental institution looking by the doors windows and a small child playing with a ball and inviting you to play with him. I always look at these experiences in a very skeptical way, because most of the times, people believes that they really saw what they think they saw (or heard)... I was working one Saturday afternoon. It was late and almost all the students and other professors were already gone, so I decided to take a break in one of the radio cabins. I took my cup of coffee, and when I arrived to the cabin, inside the recording area was a small girl, sitting on a chair in front of the microphones table, with her hands on her knees... she was wearing a white dress with a blue ribbon as a belt and blue shoes, her brown hair was held in two braids tied with blue ribbons (of course), and she was looking too the door, as waiting for somebody to cross it. When I saw her, I thought that it was very strange to find this small girl on Saturday by afternoon alone in there, but I didn't mind so much on it. Suddenly I remembered about the legend of the ghost girl, and it was very funny, because at that precise moment, she turned around her head and looked at me as she began to smile... she had a beautiful smile, and that's the last thing I saw about her, because I began to feel that annoying discomfort, so I just turned around and left the place as fast as I could. People say that this girl also appears sitting on the last corner of the photo lab, located exactly under the radio cabin.
It is great to know that we (the strange guys who loves to scare and be scared) really can write about this kind of things, as Peltablo said: This is just the best site!
