Dreaming of a burial means you have gotten rid of your bad habits or freed yourself from a negative situation.
It is a good dream that means you are finally letting go of something.
To dream of yourself or someone else being buried alive, you are experiencing some emotional turmoil.
If you dream of being buried in the earth (not in a coffin), you need to be more practical about approaching your goals. You can accomplish things, but you must learn to be more level headed.
