Oh man I'm definitely superstitious. I was driving one day and a black cat crossed the road. I literally just turned around right there. (its funny tho because now I actually have a black cat, named Binx) I refuse to walk under ladders, if I find a penny, I always pick it up, etc etc.
But I'm also a huge theater geek in school, so there's those too. Like never say good luck (you must say break a leg), you can't say Macbeth "If an actor speaks the name "Macbeth" in a theatre prior to a performance, he or she is required to leave the theatre building, spin around three times, spit, curse, and then knock to be allowed back in. "
No whistling, the theater must be closed one night a week so the ghosts can perform their plays, no real money on stage, no peacock feathers on stage, its bad luck to complete a play with no audience, and of course, a bad dress rehearsal means a good opening night.
