As we’ve all heard, breaking a mirror is said to bring seven years of bad luck— a belief that dates back to the Romans . They thought a mirror didn’t just reflect your face, but also your soul.
Because the Romans also believed that life renewed itself every seven years, the curse was thought to last exactly that long.

Walking through it was seen as breaking the sacred shape and inviting misfortune. Today, most people avoid it not only out of superstition but also for simple safety.

The superstition that opening an umbrella indoors brings bad luck originates from 18th-century England. Early umbrellas were large, stiff, and often had metal spokes.
Opening one indoors could cause injury or break household items , so the "bad luck" warning worked as a practical safety rule.

Friday the 13th

Friday has long been considered unlucky in Christian tradition because it was said to be the day of the Crucifixion. The number thirteen was also viewed as ominous, connected to the Last Supper .
When the two were combined, Friday the 13th gained its spooky reputation. Despite rational explanations, some hotels skip floor 13, and many people still avoid major plans on that date.

The four-leaf clover is a symbol of good fortune dating back to the Celts, who believed the rare leaves provided protection against evil spirits .
