The Old Man in the Rocking Chair

My parents got divorced in the summer of 1986. The following summer, my dad was staying with my cousins at their home. I went to visit him there.
One night about 8pm while my cousin and I were in a room upstairs playing, an old man suddenly appeared in the rocking chair in the corner of the room. My cousin immediately ran downstairs, but I stayed in the room, unafraid because I have had previously experiences with ghost. I walked right up next to the chair where the old man was sitting and asked," where did you come from"? He smiled in responce. Hearing a noice, I turned around expecting to find my cousin. No one was there. When I turned back around to face the old man, he was gone. He just vanished, though he looked solid, like a normal person in every detail. A couple weeks later, I was looking through a photo album and was shocked to find the very same man sitting in the rocking chair. I asked my mom who it was in the picture. She told me It was my Grandfather, who had died before I was born.
