Direct psychoanalysis:
Clothes can protect the body and cover people's soft parts and sexual organs. Dreamers can know their vulnerable parts by dreaming that a certain part of their body is not covered by clothes.
A dress can show the dreamer's actions in dealing with sexual desire and various relationships. If clothes are clean, dreamers have a healthy self-image. If clothes are dirty, it reflects the dreamer's unhealthy self-image. A dirty dress may also mark failure.
Subconscious spiritual symbol:
From this perspective, clothes represent spiritual protection.
