I mostly have rather boring dreams, and would probably enjoy a dream as interesting as yours. Except a few nights ago I dreamed that I was taking a shower and Batman walked in. I was scared and Screamed out "Aah! Batman's here and I'm in my underwear!" and then I realized "Oh yeah, most of the people Batman knows are in their underwear."

This oddly fits with the theme of your post, since a few days later I saw Batman Begins, which had Liam Neeson in it. (And was very good.)
