What are the examples of superstition?

Answer 1

Here are some:

It's bad luck to spill salt, step on a crack, break a mirror, have a black cat cross your path, walk under a ladder.

Somebody will die if a bird flies into your house.

If you say certain words, whatever you're talking about will be a jinx and the opposite will happen.

You can't win unless you wear your lucky shirt, eat your lucky meal, carry your lucky charm, perform your lucky ritual.
