This is because Swami is spooked by ghosts which are something his friends have warned him about.

He trembles at the thought of being visited by a ghost and requests to open the window to find a quick escape.

The night passes without an alarm until Swami is woken up by a stir. He looks at the window and finds a shadowy figure trying to break in.

He fears that it is the ill-famed ghost and latches on to its legs. He bites into the limbs and cries out for help.

Hearing his shriek, the family rushes to the office and the thief is apprehended.
