Cemetery/Graveyard - A cemetery is a collection of dead organic matter. It's a sad and depressing place that doesn't reflect any joy, and reflects even less hope. If someone close to you has recently died, it would be normal for you to have dreams about graveyards and death. The graveyard in your dream may be a reflection of your mood or unresolved grief. It may literally represent sadness that comes from losing someone that you love.
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 yourself and make attempts to increase your self awareness and your spiritual identity. It could represent things which require deep thinking and are not 'on the surface'. Graves could also symbolize the unconscious, and it could represent your past and long-gone experiences.

Walking through, or sitting in, the cemetery, it might be a sign that you are seeking peace and quiet. On the other hand, it could signify that you are holding onto the past. Your subconscious might draw the graveyard, if in real life you are under pressure and need to make a decision, or you are too preoccupied with your past experiences and want to bury them.
