The interpretation of this dream is not very difficult to understand. We cover with clothing our bodies already not only to protect us from the cold, but as a means of maintaining what is considered that it should not be displayed in public, the most intimate part of us.
If this meaning is translated to the language of symbols, which also operates in the dreams world, we find that the dress helps us to protect our I most internal, that we only show believe who did deserve it. See us "naked" to others , is to be exposed to know us completely, including this, our fears and weaknesses.
When we usually have this kind of dreams?... Because we often dream about situations that make us feel ashamed, and that we are not eager but run away and hide, when we are forced to adapt to new partners of studies or work, when we changed environment and we're not just very confident in ourselves and what we can bring to others. We fear inside ridicule and become evil to them.
An advice in this situation?... You face your insecurities viewing them simply as warnings unless they have more power over you. Don't let the fear of not doing well to prevent showing you as you are and everything that you can share with others.
