Dreams like this are sometimes interpreted as a fear of sexual relationships. In your waking life you need to overcome your feelings of vulnerability and learn self-confidence. Being partly dressed may symbolise that you are not prepared for what lies ahead. Thoroughly examine your plans and perfect them. Freud believed that to dream of being naked is an unconscious wish for the free unclothed periods of early life.
Most psychologists consider that dreams of nudity highlight feelings of vulnerability.
An anxious feeling may symbolise the vulnerability mentioned above but equally a feeling of approval may symbolise your pleasure at being free of inhibitions. You may be expressing your openness and honesty. If they mock you then you may be harbouring feelings of guilt and a fear or revealing your feelings. You could have a fear of sexual relationships. Indifference may suggest that something you are concerned about revealing is not really very important.
