Dreaming of an orgy means you are seeking to break out from the routine sex life that may need a little spice. An orgy is sometimes more complicated than you think to the uninitiated as every participant has to be tested and trusted. This can also indicate that you are no longer committed to one partner in the relationship and it is time to clue your partner into what you have on your mind.
The dreamer may have had problems in the real world with relationships and may be trying to resolve the problem by dreaming about orgies. The dreamer is trying to make sense of the situation in their life and at the same time find someone who shares their values of promiscuous activities.
