There is a reason why funerals are so often a part of fictional works such as books, films, and even cartoons. The rituals of a funeral - the sermon, the procession, the burial- are meaningful and they communicate to us the reality and gravity of the situation. It doesn't seem real without these elements. Accepting the reality of death is vitally important to being able to move forward after it. We cannot avoid death by avoiding funeral services. Our loss and grief are real.
