Over the years I have had many theories. Maybe I'm crazy, Somebody up there doesn't like me very much, something out there has a warped sense of humor, the angst of youth for a while but now I am only young at heart and it still is happening though not quite as often.
I have had some serious discussions with the powers that might be about this and determined that I have actually been a lot more often blessed than cursed, almost always blessed in the things that really matter, and so looked elsewhere. I am a bit crazy but not out of touch with reality so it isn't hallucinatory.
In the end, I have about decided that it is a sort of overflow of some sort of power that I think that each person has for a certain amount of control over their reality. A person is of many minds at times. Your emotions can often make you have several reactions to a single happening. You can go through mad, sad, forgiving and then sometimes laughter as you process something that at first bothered you. Sometimes for a flash, you will have a wave of murderous anger. Most people quickly set that aside and don't act on it.
We are each different and in this group, many of us have more differences from the average than you would find in most randomly gathered groups. I have over the years had several sorts of paranormal experiences ranging from clairvoyance through a few PK things, and seen things that others might not be able to perceive. When I was young I tended to see people as having a color around them that was different from person to person. I now suspect that I was seeing auras. As I got older that seemed to fade away but I still, if I think about someone, I will find myself thinking of them as being associated with a color. I think that is part of what your brain does as you age. It programs filters that eliminate the "unnecessary" bits of information. When you are driving a car you SEE the license plate number on every car that you pass. this is information that is filtered out long before it makes an impression on your mind.
Children, I believe, see, sense and maybe are able to do all sorts of things that become filtered out as they get older. My little brother was profoundly retarded and had the mind of a small toddler. He never learned to talk, couldn't feed or dress himself and was never potty trained. You could not hide from him. You couldn't hide his candy from him either. You could put it someplace and then when he wanted it he went to where ever you had put it with no way of knowing where it was by normal means. When he was little he liked to follow me around and we would play a sort of hide-and-seek but no matter what he could come to where I was and then just sit and wait for me to come out. He kept the mind of a child and so never outgrew the childlike mental state. He was also like a cat in that he seemed to often see things and be fascinated by something that no one but he could see.
In each of us there are still all those abilities that we set aside as other more important things occupied our minds. You don't need to be telepathic if you can talk and hear. Empathy is not the same as what kids seem to be able to do. They often seem to know immediately if you are a good person that likes kids or if you are a mean person that doesn't like them. you can't fool them. Later you shed this ability and replace it with experience-based and information based judgments and can be fooled.
I for several reasons have not left all of my childish abilities behind. I all too often KNOW things either before they could be known or about people that I have no way of knowing these things. I think that the poltergeist things are the result of a part of me that developed before my adult mind filtered it totally out is still active and is the cause of most of this. I suspect that it has to do with a childish way to deal with stress and frustration. My adult conscious mind doesn't allow tantrums or fits. I was always bad about repressing my feelings. I was not supposed to cry. My Dad would whip me for crying because of emotional things. I was a grown man before I learned how to cry even when my heart was broken.
That latent ability that all children have to some extent still exists in me. It is still driven by childish needs and emotional motivations BUT is now powered by an adult mind. When something happens I will try to look into the recent past and see if there has been something that bothered me to some extent that I had just "allowed" as adults do. More often than not I can spot something. as I am getting older I have more time than I used to have for the simple things. I'm retired and so can sit and think without knowing that there are a lot of things that I SHOULD be doing. This has allowed me to sort of make peace with my inner self and the poltergeist things are not happening as often. I'm also getting better at just shrugging and thinking "Whatever" when something disappears.
I spend a lot of time pondering. That is when you just sit and think while allowing your mind to wander. I have always done a lot of this but now I seem to be coming to a better understanding of myself and my past. I write a LOT. As of last week, I have written a million words in a little less than a year. When I write I seem to be able to allow a merging of my personas. This also seems to bring peace to my soul. Maybe my somewhat hyperactive inner child finds release now from us annoying people all over the world as I scatter my "humble" opinions all over the internet. Maybe my wandering missives are my therapy for my frustrations. Things are pretty good these days. My poltergeist seems to be happy with just little things like a mischevious brat than being destructive and constantly wanting attention.
I can easily believe that most poltergeist activity may be related to adolescent kids. Those are VERY stressful times as you become more personally aware and begin to chafe against the rules and restriction that caring adults place on you...and then PUBERTY hits... Some of us for various reasons carry some of this on into our adulthood. I believe that there may be a connection between this sort of activity and depression. You are trying to cope. Most outgrow this as the angst of puberty fade but some may incorporate this into their developing adult program and so have this to deal with.
