My first ever experience with ghosts took place when I was roughly 6 years old. I don't remember much about my Great Grandfather aside from seemingly random images and associated objects. I remember climbing the pear trees he grew on his land that I would routinely get stuck in and he would help me out of, the blue racquet ball I would be given to play with, and a glass topped coffee table displaying various family pictures in the living room.
It all started the day of his funeral, of which I wasn't aware of at the time. The only thing I remember about it was that my grandfather had a seizure and that they had used my blanket to try to calm him and keep him warm afterwards. From there it's a blank until the family gets together at his house later that day. I remember being told to play with a few of my relatives, but not getting along with them so I went to get my favorite blue ball to play with (he always kept it in a drawer in the kitchen.) I was too short to actually see into the drawer, but I knew it was always in the corner so I fumbled around until I pulled it out, but it slipped from my hands and rolled into the hall leading to the living room.
As I went to get the ball I noticed that the room was brightly lit with white light and my Great Grandfather was walking in or standing in front of the glass patio doorway. He looked down at me smiling and dropped to a knee with his arms open, inviting me in for a hug, but for some reason I didn't feel right and backed away from him. I don't remember what happened afterwards and didn't mention it my parents until years later in my early teens where they verified everything I told them even down to the ball in the drawer and even the placement of the furniture in the living room and knew his face from my memories before they showed me a picture of him.
Rarely, in my dreams I relive that same moment of walking into the living room... I've documented this dream on at least 5 occasions since I became aware of it. Each time seems to be more spaced apart from the last, which occurred roughly 4 years ago. I am currently 28 years old and retain all my memories and have full function of myself, but am in my younger, 6 year old body.
To this day, I have not been able to bring myself to embrace him as he seems to want. I can't say it's a feeling of fear or terror that keeps me away, but just a simple feeling of knowing something isn't right with the situation, especially knowing that I've been through the exact same experience before. This hasn't been my only run in with ghosts, but it is the one closest to home due to the special ties with the ghost involved.
