Yes, I think I do. I used to not believe that ghosts existed but I think existence is more complex than we realize.
When I lived in Hawaii on Hickam AFB (adjacent Pearl Harbor), the locals believed that spirits were on the base in certain places and did not want to go to certain houses after dark. I discounted it and thought it was just superstition and somewhat nonsensical.
But two things happened that I cannot explain to this day. The first thing was directly experienced by me: One night, around midnight, I went downstairs to get a drink of water. Everyone in the house was asleep - my two sons and my wife. When I went downstairs in the kitchen, I got my drink of water, put my glass in the sink and started to just leave the kitchen to go to the stairs and, all of a sudden, I heard this noise and, when I turned around to see what it was, it was the coffee pot that had just came on. needless to say, it was a little disconcerting to me as I puzzled what had just happened and was trying to understand why the coffee pot had just turned on. I surmised that it must have been the "on/off" switch that must have been left in a half-way position and it finally flipped over to the "on" position. I quickly turned it off and went up-stairs and decided to investigate this in the morning.
Well, in the morning, I went downstairs and tried to set the "on/off" switch to a middle position where it could possibly have been so that it could have eventually fell to the "on" side to explain what happened during the night. As much as I tried, the "on/off" switch could NOT be placed in a half-way position - it was either "ON" of "OFF"; there was no way of making it stay in-between.
To this day, I cannot explain what happened and still wonder what logical explanation could explain it.
The other incident happened to my wife, Arlene: One night as she lay in bed sleeping, she was woken-up by feeling of a hand squeezing the calf of her leg. She quickly woke up thinking it was one of our young sons. She woke up asking, "what is it? What do you need?" (thinking it was one of our little boys). There was no response to her inquiry nor did she see Justin or Taylor when she looked around the room. She then woke me up and told me that one of the boys must be awake but, when she went into their bedrooms to check on them, they were both sound asleep. She came back to bed and went back to sleep but was mystified because something clearly grabbed her leg and woke her out of her sleep.
These are the only two incidences I have ever encountered in my 47 years of being alive and they happened on Hickam AFB in the housing area where the locals believed spirits/ghost existed.
What was it? I do not know. Is there a logical explanation for it all? Possibly, but I could no longer discount a paranormal explanation either. Nothing like this ever happened before nor has it happened since so far.
I believe that there is much more to existence than we understand and even the line between life and death may be more intricate and complicated than we think or understand.
