I was outside, and I could hear some owls in the distance. I joined them in the howls and they really started talking... then I shut up and was on the phone and one howled very near me, scared the shit out of me... and I sat there... then in the far distance I am pretty fucking sure there were monkeys screaming... sounded just like chimps with that eee eee eee eeeeoooohhh hhh ayyayyya yaay ayyy noise.. creepy
