2. Kelly–Hopkinsville encounter
When it comes to alien encounters there is definitely no shortage of stories on the internet. But if you want a truly chilling account of an alien encounter than search for the Wikipedia page of the Kelly–Hopkinsville encounter. The story claims that back in the year 1955 several families reported not only seeing but touching and interacting with some ‘little green men’. One witness says that the alien beings was hanging out on the roof of the house. Another witness says that the space-man actually grabbed his hair and pulled it. If it was just these 2 people who saw the aliens then you might think it was made up but according to the Wikipedia page there were more than 20 witnesses to the alien event.
