'Pratik a professional man who had worked in an office for many years had a fearful dream. In it, he found himself in a land where small slug- like animals with slimy tentacles lived on people's bodies. T he people tolerated the loathsome creatures because after many years they grew into elephants which then became th e nation's system of transport, carrying everyone wherever he wanted to go. Pratik suddenly realised that he himself w as covered with these things and he woke up screaming.
In a vivid sequence of pictures this dream dramatized for Pratik what he had never been able to put in to words; he saw himself as letting society feed on his body in his early year s so that it would carry him when he retired. He later threw off the "security bug" and took up freelance work.'
