This is mind blowing. Your guess was just so accurate. I can only imagine how shocking that detail must have been. Knowing what goes on around one's house is very important you know? What if those aliens were the aggressive ones and the get lose off the cage or break out of the restriction, it must have been a bad sight. Taking a bold step to verify your assumption did the magic I believe @swissclive. 
I can't stand having something scare the hell out of me one day, the best I would have done in your shoes was to leave that village too. 
Did you ever find out what eventually happened after you left? I'm sure the other neighbours will just stay there in ignorance of what lies around them. The story got frightened when you gave the suspense of "something that happened next". Interestingly, you were exposed to what true aliens look like rather than some of us who have only seen them in movies. Thanks for bringing a story you have never shared to us right here @swissclive.
