To dream of your own funeral represents some circumstance that you've been dealing with. You could be trying to bury some emotions or aspects about yourself, but your dream is telling you to pay attention to them. You could be hiding from a situation and hoping that it passes. If you are close to death, then a funeral could indicate your fears and concerns about your own demise.
To dream that you are attending someone else's funeral suggests that you are putting a past relationship where it belongs: in the past. You may be releasing negative emotions you've kept for so long. If the funeral is for an unknown person, then your dream is telling you to set aside some part of your past so that a new experience or person can enter. You should think about what aspect of your life you should part with.
To dream about your living parent's funeral indicates that you need to break free of your parents' control. This dream could offer you the strength and confidence needed to gain your own freedom and independence.
