There definitely does seem to be something going on... I have had three in my clinic today with similar complaints. I wish that there was more I could do for these kinds of situations, but I have at least provided them with something to help them stay asleep longer. Just in case these screaming neighbors continue.
I have one of the doom and gloom types camping out in front of my clinic. He keeps warning me that the hour of twilight is upon us, but I have too much heart to call the police and have him removed.
