I had a very vivid dream a few nights ago. It was so vivid I woke up. I wasn't scared or anything; it was just vivid. The general thematic conflict was "Man against Martians or the Extraterrestrial". When I remember dreams I always try to analyze them. It is a great window into inner space. Like I said it was quite vivid and the amazing details that comes with the word... vivid.
To dream of an extraterrestrial being or place represents your far-fetched ideas and wild imagination. Your mind does not know any limits. Alternatively, the dream represents your desire to escape from your daily life.
