Sex 
To dream of sex represents teamwork, stability, serenity, fulfillment, affection, harmony, matrimony, relations, and adoration. All aspects of your life are in perfect balance. It can also denote that you are satisfied with your home life.
Incubus 
The incubus in a dream represents a nefarious drain of emotional resources. To be the incubus in a dream is to take strength from others through an immoral act. You may feel that you are stealing someone's success at the office by taking too much credit on a group project, but this act is improving your ego and reputation. To be seduced by an incubus in a dream is to be drained of inner strength.
Communion 
To dream of communion indicates that you are experiencing a struggle with your needs and wants. Perhaps you are trying to sort out your feelings regarding the importance of possessions versus the need for emotional happiness. This dream may also imply that someone has been unfaithful or deceptive. Perhaps you want to fit in with a group or situation.
