From the dream point of view, this is a typical compensation dream.
The burning candle symbolizes my father's fire of life in this dream.
In the dream, you didn't take good care of the candle, corresponding to what you wrote in the dream, you left him and he died.
This dream turned that deep sense of guilt into a symbol, a symbol about candles.
In fact, you should know that the candle goes out and the light goes out, which originally symbolizes the end of human life.
You found the problem in your dream and took remedial measures, which is an irreparable compensation for reality.
Please believe that your father must love you and you love him, but there are many accidents in the world that are beyond your power.
