Concealed shoes hidden in the fabric of a building have been discovered in many European countries, as well as in other parts of the world, since at least the early modern period. Independent researcher Brian Hoggard has observed that the locations in which these shoes are typically found – in chimneys, under floors, above ceilings, around doors and windows, in the roof – suggest that some may have been concealed as magical charms to protect the occupants of the building against evil influences such as demons, ghosts and witches. Others may have been intended to bestow fertility on a female member of the household, or been an offering to a household deity.

The makeup of poker's dead man's hand has varied through the years. Currently, it is described as a two-pair poker hand consisting of the black aces and black eights. The pair of aces and eights, along with an unknown hole card, were reportedly held by Old West folk hero, lawman and gunfighter, Wild Bill Hickok when he was murdered while playing a game. No contemporaneous source, however, records the exact cards he held when killed. Author Frank Wilstach's 1926 book, Wild Bill Hickok: The Prince of Pistoleers, led to the popular modern held conception of the poker hand's contents.

The evil eye is a superstitious belief in curse, believed to be cast by a malevolent glare, usually given to a person when one is unaware. It dates back at least to Greek classical antiquity, 6th century BC where it appeared on Chalcidian drinking vessels, known as 'eye-cups', as a type of apotropaic magic. Many cultures believe that receiving the evil eye will cause misfortune or injury, while others believe it to be a kind of supernatural force that casts or reflects a malevolent gaze back-upon those who wish harm upon others. Older iterations of the symbol were often made of ceramic or clay; however, following the production of glass beads in the Mediterranean region in approximately 1500 BC, evil eye beads were popularised with the Phoenicians, Persians, Greeks, Romans and Ottomans. Blue was likely used as it was relatively easy to create; however, modern evil eyes can be a range of colors.

The Flying Dutchman is a legendary ghost ship which was said to never be able to make port, doomed to sail the oceans forever. The myth is likely to have originated from the 17th-century Golden Age of the Dutch East India Company (VOC) and Dutch maritime power. The oldest extant version of the legend has been dated to the late 18th century. According to the legend, if hailed by another ship, the crew of the Flying Dutchman was said to try to send messages to land, or to people long dead. Purported sightings in the 19th and 20th centuries claimed that the ship glowed with a ghostly light. In ocean lore, the sight of this phantom ship is a portent of doom.

It is a merry and diligent creature, with an expert understanding of most watercraft, and an irrepressible musical talent. It is believed to rescue sailors washed overboard.

The miasma theory is an obsolete medical theory that held that diseases—such as cholera, chlamydia, or the Black Death—were caused by a miasma, a noxious form of "bad air", also known as night air. The theory held that epidemics were caused by miasma, emanating from rotting organic matter. Though miasma theory is typically associated with the spread of contagious diseases, some academics in the early nineteenth century suggested that the theory extended to other conditions as well, e.g. one could become obese by inhaling the odor of food.

Sriramachakra is a mystic diagram or a yantra given in Tamil almanacs as an instrument of astrology for predicting one's future. The geometrical diagram consists of a square divided into smaller squares by equal numbers of lines parallel to the sides of the square. Certain integers in well defined patterns are written in the various smaller squares. In some almanacs, for example, in the Panchangam published by the Sringeri Sharada Peetham or the Pnachangam published by Srirangam Temple, the diagram takes the form of a magic square of order 4 with certain special properties. This magic square belongs to a certain class of magic squares called strongly magic squares which has been so named and studied by T V Padmakumar, an amateur mathematician from Thiruvananthapuram, Kerala. In some almanacs, for example, in the Pambu Panchangam, the diagram consists of an arrangement of 36 small squares in 6 rows and 6 columns in which the digits 1, 2, ..., 9 are written in that order from left to right starting from the top-left corner, repeating the digits in the same direction once the digit 9 is reached.

A wedding is a celebratory ceremony where two people are brought together in matrimony. Wedding traditions and customs differ across cultures, countries, religions, and societies in terms of how a marriage is celebrated, but are strongly symbolic, and often have roots in superstitions for what makes a lucky or unlucky marriage. Superstition is often linked to practices involving luck, fate or prophecy, and while many weddings are now more focused on celebratory traditions, many are still practiced, and numerous well-known wedding traditions have roots in superstitions from previous ages. A common example of a superstition involves no one seeing the bride in her wedding dress until the ceremony.

A wish is a hope or desire for something. In fiction, wishes can be used as plot devices. In folklore, opportunities for "making a wish" or for wishes to "come true" or "be granted" are themes that are sometimes used.
A wishing well is a term from European folklore to describe wells where it was thought that any spoken wish would be granted. The idea that a wish would be granted came from the notion that water housed deities or had been placed there as a gift from the gods. This practice is thought to have arisen because water is a source of life, and was often a scarce commodity.
