I heard this story from my Aunt Yasmeen.

When my aunt was young, she had a friend named Miriam.
Sarah got a beautiful doll as a gift from her father. She loved that doll more than anything and took it everywhere as young girls do.

Now, my aunt had a male doll. As it was tradition, they both decided to get their dolls married to each other's. It was a very common back in 70's and 80's. Girls used to marry their dolls and have fun planning wedding, making dresses, and all.

But this decision was not the best decision for the life of 6 years old Miriam.
As soon both dolls became engaged to each other, Miriam started having nightmares.
A week before the wedding, once healthy, rose faced Miriam was thinas a stick. None of her friends knew what was wrong. To be honest, not many 6 year olds are that much observant.

A day before wedding, Miriam came to my aunt and told her she want to call off wedding . She says that she won't want to marry her doll to hers because her doll is not handsome. That caused  huge argument among them. Other friends, joined and all starting to blame Miriam. Girls cried because they were looking forward to the wedding.
Miriam became secluded. No one played with her. She was getting weaker and weaker. Wedding day passed. Nobody had seen Miriam for long.
One night, my aunt overhead ladies talking about Miriam being so ill that she can't even speak.
My aunt asked her mother if she can go and see her friend but grandma refused.
My aunt sneaked out and looked in from Miriam's bedroom window. Miriam was shouting, screeching at top of her lungs. Her whole body had gone dark and she looked like a skeleton.
Miriam's mother was weeping. Her father looked somber. 
Next day, Miriam was dead.

When my aunt became older, she asked grandma about Miriam's condition. And this is what my grandma told her:

"That's poor child, she suffered a lot. She actually went with her mother to gather mangoes. There was an abandoned well. She started throwing rocks in it. According to the locals, a churail lived there with her kids. Rocks killed her kids and she took her revenge on Miriam that way. Her doll became possessed.
In start, she would shout in her sleep, she woke up with scratches on her body. She would eat more than 5 people but still became weak. In the end, churail killed her.

People who knew, took the doll and then buried it in the forest. They asked churail's forgiveness. Even got Maulvi Sahab(an exorcist)  to cleanse the area but he couldn't do nothing. Then few men went near the well, shouted that they are sealing we'll in three days. After three days, well was sealed."

My aunt told me another thing. The one she couldn't tell Grandma.
She told me, "I remember seeing Miriam's doll watching me during the night from the window. She told me to stay away from Miriam. Or I'll suffer the same."
