When you dream of something or someone with a tail, and the dream focuses our attention on this, then we must pay attention to that part of the body that has been preserved by our smaller brothers and which serves for them one of the most important parts of the body: for some, the tail helps to hunt; For some it serves as a rudder to maintain balance, and for others (the lizard) it saves life when attacked by predators. In all cases, the tail is, as it were, a second personality, expressing deep emotionality (dogs, cats), rooted in the ancient history of the development of organisms. But, as we understand, Dream is a symbolic language and expression of the internal, innate characteristics of our human nature, and also, just like the tail (by analogy) has an ancient symbolic, human history of the development of our Mental Activity (soul), which makes us human, distinguishes us from animals. Based on what has been said (by analogy), it can be assumed that a tail that a person dreams of speaks of a deeply ancient, time-developed, very important part of himself. How can you call this part in one word? Yes, of course, - this is the PAST, - its Past, developed and formed; dominant long before the independence of his Ego. The past is the Mother. As the body and psyche develop, a “child” is formed - a center of volitional control and self-awareness called the Ego. The past is something we have no control over. That forgotten (authoritative) information that formed us and is now automatically present and guides us (by analogy with the mother), as before in the process of self-formation and development. But now, when we are capable of independent decision-making and the formation of our individual characteristics, the Past with its automatisms becomes, in part, like an outdated old thing and accustomed to dominating mental life - a dictator and oppositionist who does not know what compromise is. The past considers the Ego to be an incapable child who, as before, needs a “steering wheel”, i.e. a well-trodden path developed over time. Therefore, now the time has come for the Ego to begin the process of self-formation and dialogue with the past to develop a compromise. Therefore, the function of the Psyche is dreams. This is the language of the soul - a mediator, warning that the moment has come when a person (in a specific dream about a tail) is obliged and able to develop an independent decision, discarding the Past, i.e. all those habitual actions and deeds that have been developed and decide for him. Just like his mother and his parents once did. While he was still a fledgling youngster, now the time has come to establish his personal individual characteristics. This is the dream about the tail. Tail = Past.
