I assume that you are a male, and we all know that men are the givers in sexual behavior. In addition, you often dream that others sleep in your bed and get married with your quilt. So it is almost certain that you subconsciously want to be "possessed", which is naturally a sexual hint.
There is no warning, but a subconscious sexual consciousness is active. You may need a girlfriend.
If you are a married woman, this dream may be that you are subconsciously dissatisfied with your current married life. This statement may be a little abrupt. Please forgive my offense.
