At first, sorry for my grammar, English is only my third language.
About 11 years ago, when I was 5 years old, the Grandma of my father died. My Mother and I, really loved her and used to help her with everything. She also liked my Mother like her own daughter.
My mother, which is Chinese really believe in Ghosts, so I do. A few days after my great-grandmothers funeral, my mother and me sat in the living room. Our door from the living room to the corridor was a glass door. My great-grandmother used to walk trough the corridor to get in her room. As we sat there and watched TV, my Mother pointed at the door and said she saw Great-Grandmother silhouette. At first I thought she was joking, but then I saw her too. It exactly looked like my Great-Grandmother when she walked to her room. If we opened the door, to look if there's something, there was nothing, but when the door was closed, we saw her walking down the corridor again.
My Father won't believe us, but my mother and I saw her a couple of times again, but he didn't saw it, which I found very curious, because my mom and me both clearly saw her silhouette. It was really like my Great-Grandmother walks trough the corridor, and I'm sure we didn't just imagine that. After a few months, we didn't saw the "shadow" again.
Also my Mother told me that after great-grandmothers dead, she sometimes used to feel her presence, when she lay in bed, but it stopped at the same time, when her "shadow" was gone.
My Mother and I still believe that we really saw the ghost of my great-grandmother and we still wondering, why she disappeared so suddenly.
If someone have an idea, why only my Mother and I saw her, and why she disappeared so suddenly, feel free to write me.
