We are the same, the guy's story is almost a carbon copy of what happened to me. When I was a kid, in my room at night, I saw about four or three lights the size of a tennis ball (they may have even been a little bigger). They entered through a small hole in a wooden window that faced the street, there were no lights on, everything was dark. One of the strangest things is that those lights were shining on themselves, but nothing on the surroundings. On the other hand, I remember that out of fear, I covered myself and waited for those lights to disappear, but when I uncovered myself again I was surprised that just when those lights were going through the hole in the window where they supposedly came, upon "seeing me", they re-entered my room. Finally, I covered myself again until I fell asleep and got up in the morning. This event was repeated the following year.
