Lost Dreams

The other night I dreamt that I was a character on the show Lost. This wasn't the first time. In fact it was the fourth time I had such a dream. the wierd thing is that I have never seen an episode of the show. the closest I have come to watching one is an episode being on in the background while I was playing a game on my laptop. I don't think that counts. So could some one explain to me why I keep dreaming that I am on that stupid show?
