These Games That You Play Are All In Your Head
Another video to get you in the spirit of things. This is an early Tim Burton short.
I find it fascinating, not merely because it is Tim Burton and spooky (two things I like a lot both separately and together), but also because it is a pretty accurate depiction of how it is easy to give in to the thoughts in your head and how those thoughts may not be an accurate reflection of one's reality. Or rather, how one's internal, subjective reality may differ dramatically from the objective world shared with others. Also, it is fun to listen to Vincent Price's voice for five minutes.
