No Water Pressure

Kept the faucets dripping, evidently that wasn't enough. Woke up to no water pressure. Looked under the house first to see any signs of leaks. Dry as a bone. Traced about where the pipe is buried out to the well and no wet ground. Go to the well, nothing wet there and pressure gauge shows about 12 PSI. Can it be frozen with nothing busted? Well is not running. I went ahead and turned the power off. Any of you know about wells?
