As a bad thing, it is not good for yourself.
Actually, you are very lucky. Not everyone can see snakes. And you have seen so many middle-class people, you should be glad that you saw the snake earlier, and you were not bitten by the snake, so this is a good thing and you should be happy.
I hope you can live a happy life without any troubles. Everything should be optimistic. What you really see is just coincidence. If it is a dream, the Duke of Zhou is as follows:
Women dream of snakes: they and their children will get sick.
Dream of a pair of snakes: they will be separated soon.
The merchant dreamed of a pair of snakes: they could make a fortune.
Dream that a snake bit you: If you want to have good luck, your life will be rich.
Dreaming of a snake biting his wife: it is an ominous sign, and you will encounter sadness and misfortune.
Dream that the enemy is bitten by a snake: the enemy will kill each other and eventually lose both sides.
