I've noticed that when my spiritual state of mind was low (angrily thinking about someone/something etc.), a dog/dogs tended to attack me, or viciuos barking at me. Normally, they and I are friends. They would wag their tails at the distance and come to me as if we had knew each other for years. So do cats (sure, without tails' wagging ). And so do mad men. As for crazy persons I met on the street they always came to talk to me as if we were friends. At the first few times, though they didn't scare me but I still felt a bit uncomfortable. But after a while, I felt it was so normal. Sometimes, I even talked back, not only listening to them.
