Dreaming of a funeral represents that you care for the recently deceased important person in your life. It is a way of respecting them for one last time before you spend the waking hours without them around. You will close the relationship and move on with your life.
If the funeral dream turns out to be scary or you wake up shaken from the nightmare, then dreams are helping you to overcome your hate and resentments as the nightmares slowly die out in frequency.
