1. Emotional repression and unresolved emotional issues: Dreaming of your father's corpse rotting away may indicate a deep-seated suppression of some unresolved emotions or regrets towards your father, and this dream may be a subconscious processing and release of these emotions.
2. Deep Reflections on Life and Death: This dream may also reflect your profound thoughts on the fragility of life, death, and the loss of loved ones. It may prompt you to cherish the people in front of you more and contemplate the meaning and value of life.
3. The problem that needs to be faced and solved: The decay in dreams symbolizes a certain degree of decline or a problem that needs to be addressed. This dream may indicate that you have some issues related to or symbolic aspects of your father's life (such as responsibility, authority, protection, etc.) that you need to face and solve.
