This paper aims at studying the relationship between vision and dream literature. This paper takes as a starting point the notion that dream literature is a vision literature because it carries connotations and various culrural subtexts. It considers dream literature in cultural subtexts since it overlaps with political, epistemological, aesthetic and marginalized subtexts. It also views dream literature as an open literary text which overlaps with other genres. This paper examines the functions of dream literature in terms of its affinity with vision and genre.
