I do not know much about "bigfoot" but I have found that this abundance of time I have compels me to occupy my mind. I have been reading on the paranormal, ghosts and whatnot. Before I go on, you are all aware that I do NOT believe in "god", "deity" and all that. I really do not believe there are such things as "ghosts", spirits and lost-souls, at least not the way we generally think of them. However, as is my wont, I have been researching this from a more scientific position. Specifically, Quantum Physics.

You see, just because we cannot see something does not mean it doesn't exist. Human beings are limited by their five senses. Through Quantum Physics, we learn that there is a plane that truly exists that we cannot see or hear but it is there. For example, we are unable to see ultraviolet light. We cannot hear a "dog whistle". These things do exist.  Thus, we come to what many call "ghosts". I have learned that there are two basic types of "ghosts". We can define them as "real" and "unreal", if you will.

"Real" ghosts are often called "interactive". They are everywhere. They are not floating mists or half-figure apparitions. They are basically energy that is outside our sentient boundary. They do not cause fear or dread, rather, the envelope you in the "warm and fuzzies". Some call them "angels" but they are basically energy that is perceived in a spiritual manner. This is NOT paranormal!

"Unreal" ghosts are basically the crap we hear about most often. They exist, or are claimed to exist, by people that actually believe in this stuff. You may have noticed that "non-believers" rarely have occasion to meet up with this form of "ghost". No small wonder. They seem to defy the Law of Conservation of Matter and Energy because they blink in and out of existence like virtual particles. Again, Quantum Physics has a possible answer. There is a statement in QP that says, "nothing is real until you look at it."  ALL "ghosts" abide by the laws of QP.  Those that experience this type of "ghost" often say they seem to be caught in a "time-loop", replaying a scene over and over.  There is a QP equation which states, "for every 'now' that we experience, a positive wave flows into the future and a negative into the past, like ripples on the water when one throws a rock into a pond. That some people have this experience with these "ghosts" is merely a function of human consciousness. In short, a natural occurrence. NOT paranormal.

The existence of "demons" or "poltergeists" are merely a matter of abnormal psychology. As for "shadows" and whatnot, we can explain these as functions of the physiology of the eye.  So, do all these things "exist"? Yes. We can scientifically measure energy. We can prove that there is existence outside of human senses. What is really needed is to remove superstitions and religious nonsense and take a more common-sense approach.
