My grandmomma use to say, if you hear a screech owl, somebody you know will die within 3 days. She had a lot of those old sayings. She fully believed them too. More:

If the wind is out of the east for 3 days, it will rain in spite of hell.

Black wooly worms are a sign of a cold winter.

If your nose itches, somebody is coming for a visit.

I'm sure I'll remember more later.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
