A posterior appendage of animals, and of hybrid or altered human figures in dreams, associated with instinct, balance, animal nature, and what follows behind.
In dreams the tail appears in three main ways. It can belong to an animal, such as a fox, cat, or horse, where it works as a feature of the creature's character. It can be grafted onto the dreamer's own body or onto a human figure, as in a sudden tail, a missing tail, or a hybrid half-animal form. It can also appear as a general shape: something long that trails, drags, or is pulled or stepped on. Dream reports often attach vivid feeling to it, such as embarrassment at having one, alarm at losing one, or the pull of something following behind.
Humans have only a vestigial tail, the coccyx, so a tail on a human figure marks that figure as non-human or pre-human. Folklore and religious art use it as a mark of beasts, demons, shapeshifters, and spirits. Across many traditions the tail also stands for the rear, the end, or the lowest position, as in the contrast between head and tail, or the tail of a procession or a comet. In animals it also signals balance, communication, and mood.
The symbol is bound up with the body-category themes of instinct, exposure, and the animal side of human life. Because it sits at the back of the body, it can also carry associations with what is behind a person, out of sight, or left over from the past.
Jungian
The tail is read as a sign of the instinctual, animal layer of the psyche. A dreamer who has grown a tail, or who sees a tail on a figure, is seen as meeting the part of the personality that is still close to nature and not fully integrated into conscious life. Jung treated animal forms as images of libido or psychic energy, in what he called theriomorphic symbolism. A tail can mark a figure as carrying shadow material: drives that are felt to be primitive or shameful but that hold vitality. Integration would mean acknowledging this instinctual energy and not projecting it onto an animal or a demon.

Freudian
Classical psychoanalytic reading extends Freud's account of elongated, projecting objects as symbols of the male genitals, so a tail can serve as a disguised phallic image, and its loss or removal as a castration theme. Freud's analysis of the Wolf Man's dream, in which white wolves sit in a tree with large bushy tails, linked the tails to the patient's castration anxiety and to his early memories and fears. Under this reading the manifest tail hides a latent wish or fear about the body, sexual difference, and punishment. The tail would be analysed through the dreamer's own associations and not as a fixed code.

Cultural
Folklore gives the tail a wide range of meanings. In Japanese tradition the kitsune, or fox spirit, gains additional tails with age and power, up to nine. In medieval and later European iconography the devil and many demons are drawn with tails, which marks them as bestial. The ouroboros, a serpent or dragon biting its own tail, appears in Egyptian and Greek sources as an image of cycles and self-renewal. In the Hindu Ramayana, Hanuman's tail is set alight and he uses it to burn the city of Lanka. In these traditions a tail marks a being as supernatural, as a creature of power or danger, or as a figure belonging to a cycle.

Neuroscientific
Sleep research treats a tail on a human figure as an instance of dream bizarreness, in which features are combined or misattributed. Under the activation-synthesis hypothesis, the forebrain builds a story out of internally generated brainstem signals, and this can produce hybrid forms and altered body images. Dream selves often differ from the waking body, and the brain's body-schema systems are less constrained during REM sleep. Animal figures are also common in threat-simulation accounts, where predators and pursuing animals rehearse defensive responses, and in such dreams the animal's tail is incidental detail that comes with the creature.

Religious
In Jewish and Christian scripture the tail marks the lowest position. Deuteronomy 28:13 promises that Israel will be the head and not the tail, and Isaiah 9:14–15 describes the Lord cutting off head and tail from Israel, with the elders as the head and the lying prophets as the tail. The Book of Revelation gives tails to hostile powers: the dragon's tail sweeps a third of the stars from heaven (Revelation 12:4), and the locusts have tails like scorpions (Revelation 9:10). Christian interpreters have read these images as pointing to subordination, deception, and the destructive reach of evil powers. A tail in a dream is read within this tradition as a sign of lowliness or of an evil influence.
