To dream that you are naked in public and feeling absolutely fine and comfortable about it, shows that you are the person who trusts himself very much. If you feel ashamed of your nakedness or feel uncomfortable in your own skin, it means that you are really feeling very bad being yourself. The man that is naked, but only the top part of his body is uncovered shows that some death of the person you know is coming on its way. The death doesnt have to be like real death, it could mean that someone is not the person you knew before, or is simply depressed in is dead in his personality aspects. The nakedness as the sexual symbol is also known and it could mean that you have some unfulfilled desires, but simply dont know how to express it. Or you do not release your sexual energy, therefore you dream of naked bodies.
