It's not a scary as it seems. Many times dreams use death to represent a major change or transition from one stage of life to another. Dreaming of your father's death could be your subconscious mind signaling a transition occurring in your life. You may be ready for more independence, moving from the position of the child toward more adult independence. Such dreams are very natural during puberty, when approaching the end of schooling, or when considering a major life change such as marriage, moving to your own apartment , or starting a new career.
