To dream that you are transsexual symbolises your anxieties or ambivalence about masculine/feminine roles or passive/aggressive behavior. You may be reluctant in dealing with these issues. If you are considering or awaiting transsexual surgery, then the dream may represent your anxieties and fears about the surgery, recovery, and life after surgery.
To see a transsexual in your dream indicates that the feminine and masculine aspects of your Self have been damaged. You may be unwilling to confront your shadow self.
