I take it back. It is going mental. Like it's been activated. Sounds like an early warning system. Like someone is trapped down a well and it's trying to tell us but noone is listening because it's 1 in the morning. I am tempted to go and see what the problem is but I realise it's extremely cold outside and when I get to the cow there will be a communication barrier and likely very little I can do. So I'm just going to assume it's aliens and try and go back to sleep.
