Dreaming of Snakes at Night

If you dream of snakes at night, what does it mean? On the evening of September 6th, I dreamt that my father asked me to catch snakes with him, saying that he wanted to treat his nose. We caught many small snakes, and while we were catching them, a short and thick black snake suddenly appeared from behind. It almost bit me, but fortunately, I managed to avoid it.

What does this dream mean?
