A dream is a place where wish and fear meet,and when they are exactly the same.. we call the dream a nightmare.
(Again from Gregory David Roberts' Shantaram)

Some days back I wrote a blog post titled 'A Dream' and today I uploaded another post titled 'A Nightmare'. While 'A Dream' shows the brighter side of something where there is still hope , 'A Nightmare' is written from a perspective when a person loses all his hopes and lets his fears overcome them.
