You must be a very heavy sleeper. Fortunately I have dogs that alert me to anybody outside. One night I hollered at them because they were barking and I was tired. Should have gotten up, they were warning me that someone was breaking into my car. Now I listen to them.
My neighbors light is not super bright and does not go past his driveway. It’s the streetlights that light up the bedrooms. My next door neighbor is just a busybody.
I had a dog! It was a golden retriever which is useless as a guard dog! LOL
