To dream of a bisexual person may reflect conflict between masculine and feminine qualities. An aspect of yourself that is both sensitive and insensitive, passive and assertive, or controlling and compliant. It may reflect you or someone else that is playing both sides of a situation.
Alternatively, a bisexual in a dream may represent you or someone else that desires to “have it all.” It may also reflect an openness to all possibilities or choices. You or someone else that likes everything.
If you are straight and find yourself attracted to a person of the same sex it may simply reflect how nice something feels or how desirable a situation is. Ask yourself what one thing stands out the most about the person you were attracted to and how that quality may apply to your life.
