The light that shone through the window was an unbeleivably beautiful blue and looked like rays.While laying asleep at home one night in a back room I shared with my sister, I was awoken by a strange noise. It sounded like helicopter blades, rotating in slow motion. As I woke I was aware of blue light rays shining through the gap in the bedroom curtains.Scared, I tried to get up to see what it was but as I struggled towards the window the light suddenly dissapeared and somehow, exhausted through fear, I fell back to sleep never mentioning the event to anyone until many years later I related it to my younger sister who also said she had seen it. It is worth noting that the room was situated some 20-25 feet above ground level and the rear wall of the house fell directly into a back alley way. There is no way that anything as large as a helcopter could have got there and we only had a small courtyard.Not long before this event I had witnessed a fireball flying over the city in broad daylight sometime in the early evening after school.((NUFORC Note: Witness indicates that the date of the incident is approximate.
