Was awoken at 2 am by a freaky noise, like a siren. It scared the shit out of me, as I live alone and was already in the middle of a scary and realistic dream.
Turns out my iPhone had Amber Alerts set to go off. Look, I hope the kid is safe and sound after all this, but that scared the bejeezus out of me. FYI to fellow iPhoners: scroll to the bottom of the Notifications screen and set Government Alerts however you prefer. The default seems to be "on" because I don't remember asking!
