User blog comment:LadyMystery/Had a werid dream this morning. (don't read this if you actually like the tv show "king of the hill".)/@comment-4770291-20121021154048

Dreams were caused by memories, I assume but sometimes random things you don't even experienced. Your brain suddenly remembers a tv show and decided just put that little show for you while you sleep. (your dream) However, I am not sure if the brain is really "aiming" to be accurate upon remembering the whole episode or just randomly throws anything onto that memory. I have no idea. That's my assumption anyways.

You can ask, "Dream Hacked"

He's an expert on dreams. :P
