After a major rainstorm, avoid going out a night worms might crawl up your legs. I have a small fear of worms so when I see them crawling on the ground, especially after a hard rain, I try to avoid them -walk over them, away from them, etc..
When I was young, I went to the farm with my mother. A green baby snake wrapped itself around my ankle and I didnt' sense it..know it but my mother said, "oh my daughter, you have a baby snake wrapped around your ankle, let me take it off." I glanced down and sure enough, I saw it. I think that sort of traumatized me a little bit. So I never really like snake and worms.
