Bats use high-pitched sounds to navigate (they don't see well, so they use a sort of "sonar" to help them avoid obstacles and find food). the
creepy noise you heard could very well be the bats' "echolocation".
Also, it's possible you've misjudged the size and distance of the things. Even trained pilots have great difficulty estimating distance and size in
the night sky. There just isn't enough information to accurately gauge how big something is.
