Is it lucky to find a small snake in the bed at home?

That depends on what color the snake is. If it is red, it is not good. It's a bad omen, indicating that your family will have a river of blood in two years.

It's no big deal if it's another color.

If it is red, find a yin and yang teacher to do it quickly.

But don't worry too much, you can't say for sure about this kind of thing.
