To dream of plastic surgery represents deliberate changes to your personality or beliefs. You may be rebuilding your self-esteem or attempting to redefine yourself.
Negatively, may be a sign that you are not being yourself, are trying too hard to impress people, or that you don’t like yourself.
Example: A woman dreamed of getting for a tummy tuck and liposuction on her legs. In waking life she was getting a divorce. The plastic surgery in this case may have reflected her feelings about getting a divorce helping her to redefine herself as independent from her husband.
