Psychoanalysis:
Dreaming of his father's death doesn't mean that something really sad will happen, nor does it imply that you want your parents to get hurt. Generally speaking, this kind of dream is triggered by the changes you are experiencing.
Usually hint: You are no longer a child, and your relationship with your father is not what it used to be. But that doesn't mean that there is no relationship between you and your father or that the relationship has deteriorated. This just shows that when a period is over, your father and you will start a new life.
