We always see a common question about dreams that "Do you dream in color?" but suddenly a question came to my mind as to what does a blind ( by birth ) human see in his dream ?
Do the Blind Literally "See" in Their Dreams? A Critique of a Recent Claim That They Do : http://psychology.ucsc.edu/dreams/Library/kerr_2004.html The Dreams of Blind Men and Women: A Replication and Extension of Previous Findings : http://psychology.ucsc.edu/dreams/Library/hurovitz_1999a.html
I followed both links given by SaswatPadhi. They confirmed what I always thought. To put it simply, blind people do dream but not in pictures.
