In Indian dances, the dancer wears an ornament which creates sounds like small bells tied together to form one sound. So this story was told to me by my father.
At the time when my grandmother and grandfather moved in with their son, my house had one floor then roof on the top like most other houses at that time. In India it is said that before you start living in a new house you have to do religious ceremony which includes a priest, who asks the evil spirit in the house if any to leave. But my grandfather thought there was no need of it so they came in the house and started settling their stuff.
Everything went smoothly through the day but at night when they went to bed, they heard the sound of the ornament which dancer wears from the roof. So my grandmother got very scared and asked my grandfather to check the roof if there was somebody there but he found no sign of even an animal. That night they took it lightly and assumed that it might be coming from the neighbours'. The very night they heard the same sound and this time it was louder than yesterday.
This phenomena kept on happening for the whole week and disturbed them so much that they were not able to sleep. My father also told me that one night he, with a stick, went to the roof to catch the ghost but that night the ghost didn't show up so he was really very disappointed. The next night when my father was in bed the sound came again and this time the sound was so loud and hard that they thought it would penetrate through the ceiling.
The next morning my grandfather called a priest who did the ceremony in the house and they heard a scream of a girl and then complete silence. After that night no sound came from the roof and for the first time they had a good night.
I have had an experience of walking down a dark road, hearing the sound anklets following me. Seriously. I have posted it over here in YGS.

We have to first eliminate the most plausible causes of such noises - such as "Crickets" which of course do make such sounds similar to anklets.
I don't know about the scream.
Perhaps your grandparents added that bit to exaggerate the experience.
Elder's tales should always be taken with a pinch of salt.
Maybe perhaps it was a real haunting.
Depends on the storyteller (not you gamerx) to provide the actual data without the spice or masala.
