Graves are generally depressing and represent some form of death. On a very physical level this dream does not appear to be a very happy omen. However, the dream could also have deeper and more spiritual meaning. It could represent things which require deep thinking and are not “on the surface.” Graves could also symbolize the unconscious.
If someone close to you has recently died, it may be normal for you to have dreams about graveyards and death. However, if this dream is coming up and there has been no death in the family, consider your feelings in daily life.
If you are feeling depressed or helpless in any way, “look inside” and make attempts to increase your self awareness and your spiritual identity.
