Are you superstitious?  I didn't realize that I'm kinda superstitious. Actually more then I thought! Here are some common superstitions and their origins!

I'm so guilty of Knocking on wood but I never knew where the superstition came from! According to Live Science and

Knock on wood

The fixation on wood may come from old myths about good spirits in trees or from an association with the Christian cross. Similar phrases abound in multiple languages, suggesting that the desire not to upset a spiteful universe is very common.

Cross your fingers

Those wishing for luck will often cross one finger over another, a gesture that's said to date back to early Christianity. The story goes that two people used to cross index fingers when making a wish, a symbol of support from a friend to the person making the wish. (Anything associated with the shape of the Christian cross was thought to  be good luck.) The tradition gradually became something people could do on their own; these days, just saying "fingers crossed" is enough to get the message, well, across.

Throwing a coin into a well to make a wish.

Since wells are a source of water, they symbolized fruitfulness.  So if a woman stood by a well and made a wish, it was supposed to come true.  And back then she usually wished for a husband and children.

Kissing under the mistletoe

It's thought to have originated at ancient Greek festivals, as a way to ward off evil and welcome love into people's homes.

Throwing rice at the bride and groom. 

It comes from ancient Hebrew and Egyptian cultures, and is a symbol of fertility and good fortune.

Careful with that mirror

According to folklore, breaking a mirror is a surefire way to doom yourself to seven years of bad luck. The superstition seems to arise from the belief that mirrors don't just reflect your image; they hold bits of your soul. That belief led people in the old days of the American South to cover mirrors in a house when someone died, lest their soul be trapped inside.
