I ponder while hint that quite possibly maybe in fact I have. The generalized notion for a ghost is the spirit of and/or soul of the dead that appears and is witnessed by the living. When unsure I like to ponder the antithesis. Could that be the living appearing to a spirit. One may ponder which is the ghost of disbelief becoming believable. Of course then one may inquire of angels. Do angelic beings have privilege to seeing both spiritual entities and living entities. hmmmmm . . . I wonder if that gets confusing for them.
I believe there is the body, mind, soul, and spirit for a person. I speculate how many of those mammals or even any of the animal kingdom in general may have. Ever wonder about your cat having nine lives?
Could it be the human species is privilege of all four while maybe other mammals are missing one of those four? A reptile enjoys possibly only two. It gets really interesting when one considers the human species brain is said really to be three joining together becoming a fourth - reptilian, limbic, and neocortex. Alas, I wander in thought . . .
Have I ever seen a ghost? Firstly, to answer that question is first to know of whom the ghost is of. If I have never met the person, of which there is a spirit, then how would I know if a ghost or not if made avail to my senses? For instance maybe I have met the ghost of Alexander the Great, yet simply do not have the capacity or ability to recognize the very fact whom I met is in fact a ghost since never meeting Alexander the Great much less knowing him.
Do I believe in ghosts? Since I believe as shared a person of human form has a body, mind, soul, and spirit then I assuredly I must answer with yes since by definition a ghost is a spirit. Difference shared by definition is that spirit reveals itself through some means.
Have I seen one? I have to say most likely, yet I have no proof or of the least proof that is acceptable possibly even of this 'self'. After all I did not know Alexander the Great.
Do I feel like I've communicated with someone who has passed away. The definition for communication is the exchange of information or express feelings, thoughts, or ideas with someone using words, sounds, signs, or behaviors. I always wonder about this especially when my computer is acting up both on the internet and off. I just wonder. Of course I am simply weird to begin with. I think funny things like some butterflies and birds are angels in disguise. Aren't hummingbirds simply amazing :-)
