Nakedness
Nakedness typically refers to a persona problem or a spiritual quality. As always, understanding the context is crucial. For example, being naked at work likely indicates a persona issue, while walking naked to an illuminated hill probably has a more spiritual meaning. Being in a situation without clothes or only in underwear may also point to difficulties with adaptation.
It’s worth noting that nakedness can be expressed in ways other than being completely without clothes, such as entering a place fully dressed but barefoot. (Christian pilgrims early on abandoned nakedness, opting instead to walk barefoot with loose hair, which carries the same symbolic value.)
Persona
If one dreams of being naked in social situations, it generally concerns a lack of an adequate persona or a fear of being exposed as a fraud (which would also be a persona issue). It is common, for instance, for relatively successful students and professionals to see themselves as impostors, afraid of being found out. The term "stripped" aptly describes the feared scenario.
The motif of being naked among clothed people is often tied to the circumstance that only the dream ego cares about this; the surrounding people are entirely indifferent to his nakedness. This may reflect the dreamer’s fear of exposing himself, while in reality, no one else would care. We almost inevitably exaggerate our own complexes while scarcely noticing others’. What is embarrassing to one person is indifferent to another.
We almost always wear clothing that reflects our culture, both broadly and within specific contexts like workplaces or certain events. With clothing, we are never entirely ourselves but instead present as cultural beings. Taking off one's clothes is, therefore, a way of shedding what is not one’s true self. This was not uncommon in initiation rites.
Analysis
To be "stripped" is something most people fear, but being stripped is a part of analysis. (Mysterium Lectures, p. 68.) In analysis, this happens in a safe environment, not in public. The point is that a dream image can have either a negative or a positive meaning depending on the context. Here, it involves an exposure that allows for transformation; one leaves with new clothes.
Vulnerability
Being without clothes makes one vulnerable, as though clothes were armor. In reality, if one were naked or lightly dressed among well-dressed people, one would likely feel exposed and defenseless. In other words, nakedness in dreams can refer to a feeling of weakness in relation to others or, in other contexts not necessarily involving others, a sense of being unprotected. However, this vulnerability can be either positive or negative, conscious or unconscious, depending on the situation.
Unreserved
Being naked is also a symbol of being without reservations: innocent, open, and unconditional. These states are sometimes described as prerequisites for reaching higher states of consciousness or enlightenment. Taking off one’s clothes can symbolize the baring of one’s soul. Naked children, in particular, are symbols of such qualities.
The True Self
To be naked is to simply be oneself. It is the naked truth, a "natural state"; undressing sometimes alludes to revealing one's true self, one's soul. In some contexts, nakedness symbolizes rebirth—we all come into the world without clothing. This theme relates to mortificatio, the part of the work where the body dies (to be transformed/reborn).
Unconsciousness
As is well known, Adam and Eve were naked until they ate from the Tree of Knowledge; this made them self-aware, and they immediately covered themselves. Children have no issue being naked among others until they reach a certain age—or a certain level of consciousness, one might say. Thus, nakedness can also symbolize a blessed unconsciousness that one outgrows ("the primordial state") and, in a sense, something to which one may return.
Spirituality
Clothing can symbolize being trapped in a certain situation defined by humans, by time, and by space. Deities, such as the Graces, are sometimes depicted as naked because they are free from the constraints of time and space. However, deities who walk the earth are rarely depicted or described as naked. That is, if the deity is "beyond," it is naked; but if it is temporarily bound to the earth and time, it is clothed.
Similarly, there are Gnostic notions that humans must shed their earthly garments to enter heaven, naked; and Jesus, after all, says that one must come as a child to enter the kingdom of heaven (Matthew 18:3).
In a vision, Meister Eckhart saw a naked child. The boy, according to the dialogue, belonged to God; he said he was "a king." Meister Eckhart offered him clothes, but the boy replied that if he accepted them, he would no longer be a king and then disappeared. In other words, as naked, he belonged to the other world, but if clothed, he would belong to this one.
