Mythology

Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths.

The main characters in myths are usually non-humans, such as gods, demigods, and other supernatural figures.

Disguise 

A disguise can be anything incognito which conceals one's identity or changes a person's physical appearance, including a wig, glasses, makeup, fake moustache, costume or other items.

Costumes are usually intended to change one's identity so that they appear to be a certain fictional character and can assume the role of that character. 

The concept of the human guise is often used by various shapeshifting mythical beings, such as supernatural creatures and deities, to test or fool humans, or allow themselves to pass amongst them without suspicion.

In mythology, folklore and speculative fiction, shape-shifting is the ability to physically transform oneself through an inherently superhuman ability, divine intervention, demonic manipulation, sorcery, spells or having inherited the ability. The idea of shape-shifting is in the oldest forms of totemism and shamanism, as well as the oldest existent literature and epic poems such as the Epic of Gilgamesh and the Iliad. The concept remains a common literary device in modern fantasy, children's literature and popular culture.

Archetype 

a collectively-inherited unconscious idea, a pattern of thought, image, etc., that is universally present, in individual psyches.

Jungian theory a primitive mental image inherited from the earliest human ancestors, and supposed to be present in the collective unconscious.
Psychologist Carl Jung defined an archetype as “a universal and recurring image, pattern, or motif representing a typical human experience.”  In a sense, archetypes are an encoded energetic structure that lies within our unconscious but may be accessed as a tool for transformation and healing.  It is relatively modern phenomenon that archetypes have been labeled or identified and yet, just as with animal totems, they have been present in many cultures through artwork, stories and mythology since recorded history began.

Each individual is said to have a complex blend of a few archetypes, which can gradually develop and change over time due to our life circumstances and personal growth. These archetypes provide general explanations for our various methods of feeling and reasoning. In Jung's psychological framework, archetypes are innate, libidinally collective schemas, universal prototypes for idea-sensory impression images and may be used to interpret observations. Jung treated the archetypes as psychological organs, analogous to physical ones in that both are morphological constructs that arose through evolution

A power animal

is a broadly animistic and shamanic concept that has entered the English language from Anthropology, Ethnography and Sociology.  In the shamanic world, everything is alive and connected, bearing an inherent virtue, power and wisdom. Power animals represent a person's interconnection to all life, their qualities of character and their power, their inner self.Allegedly we all have power animals that are connected to us much like spirit guides. They come in all shapes, sizes, and frequencies bringing something special at the time we connect. In shamanism power animals often shape shift making an experience more profound. They guide your journey into awareness, by unraveling secrets lost in time to discover the nature of reality and where it is going especially in today's world where people and experience make less sense each day and answers are often found beyond physical reality.

Power animals most often appear to humans in dreams, meditations, initiations, and vizualizations.
