Halloween Superstitions: 13 Spooky Beliefs About Luck and Bad Omens

Halloween superstitions have a way of turning ordinary things into signs. A black cat crosses the street. A mirror breaks. Salt spills. Suddenly, someone is wondering whether the universe is trying to say something.

Most of these beliefs are much older than modern Halloween, but the season has collected them all: witches, unlucky numbers, strange animals, protective rituals, and symbols that supposedly bring either good fortune or trouble.

Of course, superstition cannot change a random outcome. But that has never stopped people from enjoying a good lucky charm, or avoiding an ominous sign just in case.

Here are 13 spooky beliefs that still follow us around every October. And keep reading: 25 Free Spins are waiting for Exclusive Spin Club members further down the page.

1. Black Cats Bring Bad Luck

Few Halloween superstitions are as recognizable as the black cat.

For centuries, black cats were associated with witches, magic, and the supernatural in parts of Europe. That eventually helped create the belief that crossing paths with one could bring bad luck.

But the story changes depending on where you are.

In some cultures, black cats are actually considered symbols of good fortune.

So perhaps the cat is not unlucky. Maybe it just has an image problem.

2. Breaking a Mirror Means Seven Years of Bad Luck

Drop a mirror and you may hear the famous warning immediately:

Seven years of bad luck.

The superstition is often connected to old beliefs that mirrors reflected more than your appearance, they could somehow represent the soul or life itself.

Why seven years? Seven has long carried symbolic meaning in many cultures, and later traditions helped attach that specific number to the broken-mirror belief.

The practical problem, of course, is still the broken glass.

3. Walking Under a Ladder Is Unlucky

Walking under a ladder is usually a bad idea for practical reasons.

Superstition gives you another one.

One explanation links the belief to the triangular shape created by a ladder leaning against a wall. Triangles have held sacred meanings in different traditions, so passing through one was sometimes viewed as disturbing that space.

Whether you believe the story or not, walking around the ladder is probably still the smarter move.

4. Spilling Salt Brings Trouble

Salt was once extremely valuable, which may help explain why wasting it developed such a bad reputation.

Eventually, spilled salt became associated with bad luck.

The traditional fix?

Take a pinch and throw it over your left shoulder.

Does it reverse bad luck? No evidence says it does.

Does it make the kitchen slightly messier? Definitely.

5. Knocking on Wood Protects Your Luck

Said something optimistic?

Quick – knock on wood.

This familiar good luck superstition appears in several cultures and may be connected to old beliefs about trees, protective spirits, or sacred natural objects.

Today, most people use it almost automatically.

“I haven’t been sick all year.”

Knock on wood.

“My team hasn’t lost at home.”

Knock on wood.

Some superstitions survive because they are simply too easy not to do.

6. The Number 13 Is Unlucky

Hotels sometimes skip a 13th floor. Friday the 13th has its own horror franchise. And plenty of people would rather choose almost any other number.

Thirteen has become one of the most famous bad luck superstitions in Western culture.

There are many theories about how it developed, including religious and historical associations, but there is no single explanation everyone agrees on.

And not everyone avoids it.

Some people deliberately choose 13 as their lucky number precisely because everyone else thinks it is unlucky.

Numbers can carry completely different meanings across cultures, as we explored in our guide to lucky numbers around the world.

7. Horseshoes Bring Good Luck

The horseshoe is one of the classic symbols of good luck.

For centuries, iron itself was sometimes believed to offer protection, and horseshoes gradually became popular charms placed above doors.

There is even disagreement about which way they should hang.

Some say the open ends should point upward to “hold” the luck.

Others turn them downward so the luck can pour over anyone walking underneath.

Apparently even good-luck traditions need house rules.

8. Bats Are Signs of Something Supernatural

Bats fit Halloween almost too perfectly.

They fly at night, live in dark spaces, and have long been connected with mystery, fear, and the supernatural.

Their later association with vampire stories only strengthened the image.

In reality, bats are simply nocturnal animals doing what bats do.

But silhouetted against a full moon?

That is a different story entirely.

9. Owls Can Be Omens

Owls have carried very different meanings across cultures.

They can represent wisdom and knowledge, but in some traditions they have also been connected with death, spirits, or warnings.

Their nighttime habits probably did not help.

An animal that silently watches you from a tree in the dark was always going to attract a few stories.

10. Ravens and Crows Predict Trouble

Dark feathers, sharp intelligence, and a talent for appearing in dramatic places have given ravens and crows a long history in folklore.

In some traditions, they are seen as messengers or signs of approaching trouble. In others, they represent intelligence, transformation, or even protection.

Either way, they have excellent Halloween branding.

11. Witches Fly on Broomsticks

The witch on a broomstick is one of the most familiar Halloween symbols in the world.

But the image developed gradually through European folklore, art, stories, and later popular culture.

By the time Halloween became the celebration we know today, the combination was already irresistible:

Pointed hat. Full moon. Broomstick.

No explanation required.

12. Jack-o’-Lanterns Keep Bad Spirits Away

Carving pumpkins may feel completely American today, but the tradition has older roots.

Early versions of jack-o’-lanterns were carved from vegetables such as turnips and connected with folklore about wandering spirits.

When the tradition crossed the Atlantic, pumpkins proved much easier to carve.

The result became one of Halloween’s most recognizable traditions.

Whether your pumpkin actually protects the house is another question.

But it certainly improves the porch.

13. A Lucky Ritual Can Change What Happens Next

This one extends far beyond Halloween.

People wear lucky clothes, choose favorite numbers, repeat certain routines, and avoid particular actions because they feel connected to good or bad outcomes.

Casino players have their versions too.

But when you are playing an RNG-based game, a lucky object, number, time of day, or ritual cannot change the next random result.

That does not mean you cannot enjoy the tradition.

Keep the lucky shirt. Tap the table twice. Choose number 7 because you like it.

Just keep superstition where it belongs: in the fun, not in the strategy.

If you enjoy the lighter side of superstition, take a look at these lucky casino habits and pre-spin rituals players enjoy.

Why Do Halloween Superstitions Survive?

Because they make ordinary moments more interesting.

A black cat becomes an omen. A horseshoe becomes protection. A number suddenly feels powerful.

Humans have always told stories about luck, danger, and the unknown, and Halloween gives those stories the perfect season to come back.

You do not have to believe them to enjoy them.

And sometimes saying “just in case” is half the fun.
