Something inside you has died and you should find out what it stands for and why it has appeared in the subconscious. Also, this dream invites you to reflect over a terminal state, about what it means for your mortality. If it repeats a lot, it could be an indication of neurosis. Assuming that you see your own body in the tomb, it means that you are restructuring your life. Generally, the dream foretells a profound change in your existence. Superstition says that you experienced a loss, but not necessarily death. Maybe you are dying spiritually and you will later be reborn. The celtic people considered cemeteries the uterus of Mother Earth, and that in them new spiritual life is born. Other interpretations claim that this dream foretells deception, and, curiously, news about a marriage.
