"There have also been reports of the Baoli being haunted," says Wikipedia.

"It is one of the most haunted places of India. People often call it 'Baoli of the unseen' (Baoli means 'center of attraction').
They believe that evil spirits reside here. It is said to be filled with Black water once. Rumor has it that it attracted the depressed hearts towards itself and hypnotized them to jump into the water.
Every time when it absorbed someone, the water level raised." - www.tripoto.com
