Dreams of watching TV?

So I had a very strange dream last night, one that doesn't occur very often, or at least ones that I don't remember. Basically I had roughly a 20 min vivid dream of me and a bunch of mates watching an anime. That was it... I was basically lying on the floor for quarter of an hour (that's probably how much it felt like) staring at a TV screen. What? Anyone else had a dream like this?

I do. Sometimes, since I play videogames a lot, my dreams are fullscreen (if that makes any sense.) I am often watching movie trailers. I can hear the announcer and stuff.
