This was my first encounter with a ghost, and the only one that I cannot say to myself "well MAYBE it was just this or that". I know what I saw. This is not a scary experience, so if that is what you are hunting for I'm afraid my story is not for you. It is absolutely true though.
I was young, around 8 or 9, I honestly don't remember how old I was but it was around there. I was in West Virginia with some family as my great grandmother had just passed. We were at my great aunt's house, her house was set up a bit strange as it was not a very big place, but it had two kitchens... One upstairs, one downstairs. We always stayed downstairs as there was more room down there and it had a more cozy feeling compared to the "fancy" kitchen/dining room upstairs. My aunt always kept more food in the downstairs fridge, where the upstairs one was filled mostly with drinks.
Anyway, I was given permission to go upstairs and get myself a soda. Going up the stairs put you at the end of a hallway, to your right is the kitchen, left leads to the front door, straight ahead leads to bedrooms, a bathroom, and one little room that was kind of a living room area. There was a small couch, a rocking chair, tv, etc. For some reason I walked straight past the kitchen and stopped in the hallway directly outside of the living room, realizing what I had done, I went to turn around and my eyes scanned past the living room. I thought I saw something and did a double take. Sure enough, my great grandmother was sitting in the rocking chair looking toward the television. I stared at her for a moment before she turned her head and looked at me with a smile, I looked for a couple more seconds before turning and running back downstairs.
I was scared when I saw her, but I in no way felt threatened... My fear came from my mind not being able to understand what I was seeing, I understood what death was at the time, I knew she should not have been there. It is now a comforting memory I have though, as I can still clearly picture her smiling at me.
So that's it, I appreciate anyone who read this knowing that it would not be a horror encounter. I also know that many of you are just dying to know (as I would be) if I got my soda... Sadly, I did not.
