Ravana kept Sita as a prisoner, in a garden, in Lanka. Among the rakshsis guarding her was an old and wise rakshasi named Trijaata.

One day, she said to the other rakshasis, "Leave Sita alone, for I have seen a bad dream." Trijaata told them that she saw Rama and Laxmana riding towards Lanka on their pushpak vimaan with Ravana's body hanging from it. She said that Ravana was dressed in a black robe and drinking oil. Sometimes laughing and sometimes crying, Ravana seemed to have gone mad.

She said that she also saw Ravana's sons and all the rakshasis going southwards riding on pigs while Vibhishana, dressed in a white robe, was the only one flying safely across the skies. Trijaata added that she later dreamt Rama , Laxmana, and Sita shining bright as the sun going northwards on a four tusked elephant. Finally, as the gods rejoiced, Lanka sank into the sea.
