Question: Have you ever seen a ghost?

Answer:

Yes many, too many to list here but let me start with one who came back into my life recently. To begin with, my wife and I were visiting and area called "Chota" in Monroe County Tennessee. At Chota, there were several graves honoring Cherokee chiefs who had died there. The graves had been moved when a dam was created and the Cherokee town had been flooded out of existence. After paying our homage to those buried there,  we loaded up and headed home. As I drove, I checked the rear view mirror, and nearly ran off the road.
There, plain as day and looking like a regular person sitting in the back seat, was a native American. He was an old man, wearing an unusual hat and an odd curved breastplate. I pulled off the road and told my wife but, by then, he was gone. Later, after we got home, I glanced at a movement in a hutch in our living room and there he was again. This time, my wife saw him as I did (she sees ghost more often and more clearly than I, although I can talk to them more readily. 
I asked him who he was and he responded he was called "the father" and would not expound further other than admitting to being a Cherokee Leader. For a while after that, he disappeared from sight for a time. After a couple weeks, my farmer neighbor and I had a discussion about what I do for a living. I told him that I was a psychic medium. He allowed that he didn't believe in them but didn't see anything wrong with the occupation.
About a week later, my neighbor came careening into out driveway in his old pickup truck and screeched to a stop. He jumped out of the truck and ran to where I was standing on the porch. He looked like, well, like he had seen a ghost. Turned out, that he had. "What does a ghost look like?" were the first words out of his mouth. I explained that they can be translucent, a ball of light, or look just like you or I. He then told me the story of how he was walking through his home when he came upon an old native American in his hallway. Thinking that the old man had broken in he yelled, "What are you doing in my house?" The old man simply smiled at him and vanished into thin air.
A while later, a friend of mine was staying over night in a storage building apartment my brother owned. Bear in mind that this apartment had a one barred window and one door which locked from the inside in a metal building. As my friend readied himself for bed, he felt someone sit down on the bed. For some reason, he thought I had somehow snuck back in to startle him which, of course was impossible to carry off in this instance. So, he turned and looked at the other side of the bed. Sitting there was, yes you guessed it, an old native American in a funny hat and an odd metal breastplate. Needless to say, after the old man disappeared, he quickly dressed and drove the two hour drive home.
Okay, fast forward about ten years, I was working on my geneology and had gotten to my six times great grandfather who, as it turned out, was a Cherokee Chief. His name was Ostenaco. I researched him through location and date of birth and low and behold, I found a picture of him. He was a younger version of the old man I whose ghost I had seen and who called himself "the Father".  He was replete with the same hat and metal breast plate that I had seen on the ghost who had visited us and others. He was truly, the father.
