That's kind of funny to me. When we were kids, (my siblings & I) I clearly remember us talking about the fact that no matter where we moved, we had some kind of ghostly encounter. We moved around a lot.
We all experience "weird" phenomenon in our lifetime. Most people do what I was doing. When it happens, you try to explain it away, was it a dream? Was it something explainable like, the house settling or maybe the furnace knocking? Maybe it was just eye strain or some kind of light/shadow effect. The marks and bruises must be from something I just forgot about bumping into or didn't notice occurring. My aches and pains must be from aging? Or maybe I just slept funny? Then, when you've exhausted all theories and you still can't come up with an explanation, you shrug it off and file it away in your mind as something strange and inexplicable and just move on, try to forget about it. I got to the point where my "file it away" folder became overwhelmingly full.
There inevitably came a day that I had to sit myself down and decide what the heck was happening to me. Was I crazy, or is this really happening? I sought professional help. After 20 years of trying every kind of medicine & having every kind of medical testing known to man done to me. I purposely avoided any kind of research on my phenomena in that time period because I didn't want to be influenced by any outside sources. I wanted to present facts only, just my own personal experiences. The conclusion is... I am not seeking attention, I do not have a personality disorder, as far as the world of psychiatry and medicine is concerned, there is nothing wrong with me. They have no explanation either.
I remember when I first started seeing a psychiatrist and I was telling my sister that the doctor thought it may be a form of schizophrenia. She said no, you are not schizophrenic. As I was getting up and walking to the kitchen to fill my water glass, I said ya, I know. Then I stopped, turned and looked at her and said, but, that's exactly what a schizophrenic would say, right? She took a deep breath, turned red in the face, started laughing so hard that she fell out of her chair.
Anyway, my conclusion is that I am not seeing ghost or spirits that follow me where ever I go. It is extraterrestrial/interdimensional beings. They are real and they are here.
