To dream of a bikini represents you or some aspect of your personality that is totally focused on confronting uncertainty or a negative situation. The feminine aspect of the symbol may be a sign that you feel powerless or out of control as you confront problems.
The symbolism is based on water reflecting uncertainty or negative situations. The bikini then reflects your personality that is dealing with this.
The color of the bathing suit is very important. Blue represents a positive outlook, red is negative, and white symbolizes purification.
Example: A man dreamed of seeing a girl in a bikini at the beach. In real life he was confronting a serious health crisis in which he believed he was going to die. The girl in the bikini symbolized his sense of powerlessness to cure the problem while confronting the uncertainty of death.
