Dreaming of a coffin is a symbol of good luck. Dreams are the opposite of reality.
Sometimes terrible things in dreams can be a good sign.
Dreaming that the ashes will be moved to the grave means that some bad emotions in your heart will disappear or your secrets will be hidden.
Then I dreamed of ghosts.
Dreaming that ghosts have no intention of attacking themselves means that you can avoid the disaster that will happen.
Ghosts themselves represent bad things.
If a ghost sees you and doesn't attack you, disaster will befall you or people around you.
Maybe it's because you've been under a lot of pressure recently that you dream about ghosts. Relax yourself moderately, and maybe you won't dream about ghosts.
