This story dates to my younger days and occurred in my grandparents' house, located in Mathura, UP. My grandfather bought this old British mess/building in the cantonment area and my mother and her siblings (uncle and aunts) have grown up in the house. There have been multiple incidences of sightings in this house and those will be shared separately at a later time. This incident occurred with me when I was around 11 years old.
The house and the garden was surrounded by white brick wall. My grandmother had a small vegetable garden at the very end of the grounds, separated from the rest of the lawn area by big bushes. This vegetable garden ended with the white brick wall which was around 6 feet tall. The remaining grounds had big trees like neem, peepal and fruit trees and we used to love climbing them.
It was around 6.00 pm and still light outside. My cousins, myself and my sister were playing hide and seek. I was trying to find my cousins and sister. I went out of the house thinking they were hiding behind the bushes. As I was looking, I saw a small girl wearing a white dress and hair tied in a pigtail run towards the back of the garden. I thought it was my sister so I ran after calling her name and telling her I saw her and she was out. But the girl did not stop and kept running towards the vegetable garden. I followed her running trying to catch her. At this point I was getting angry, since she was not stopping. In a few minutes she started walking rather than running and her strides were still bigger than mine and no matter how hard I ran she was always 3 feet ahead of me. Suddenly she stopped in the middle of the cauliflower patch and turned to look towards me. I was very surprised to see that it was not my sister but a much fairer girl. Her skin was white and she looked ill. I asked her who she was and how did she get in because the gates were normally locked to prevent us kids from running out on the road. She pointed at my grandmother's house but did not say anything. At this point my aunt came out and asked me to come inside, I turned to tell her that I will be in a moment. It would have taken me 30 seconds to reply. By the time I turned back and the girl had vanished. I looked for her but I could not find her. She did not pass me to go back towards the house or the remaining ground to hide behind the trees and she couldn't have climbed the big wall. I went inside and told my mom, who told my aunt. My aunt told me that they used to see the girl when they were young too and once had been told by the girl that she wanted to play and that she was sick. They also said that the little girl ghost liked mangoes and would sometimes sit on the mango trees to watch them (my aunt and her siblings play). My mom said they stopped seeing her when they became teenagers.
I got very scared after that and told my mom that I didn't want to see her again. Funny enough, I never did. My younger sister saw her multiple times and even played hide and seek with her. The girl never harmed us or tried to scare us, she was simply there. My sister stopped playing with her and seeing her when she turned 13. My cousins have also acknowledged to see her and play with her while growing up. I have never been back at the house since my grandparents death and I wonder if she is still there and if I take my children there now, will they see her.
I see it as a beautiful experience, but sad at the same time, because like others said, it is sad that a child became trapped, without being able to do what kids normally do. I find it beautiful that you, kids, were not afraid of her, I think it was a happy time for her too when you were playing with her and showing her that she can be seen and communicated with.
I don't think it would be a frightening experience for your kids seeing her. I, as achild, I had some encounters which did not scare me at the time but if they were to happen to me now, I'd surely run.
It is beautiful, as well, how she'd been there and making herself present to different generations.
