When I was 11 years old my friends and I were playing blind man's buff during a sleepover when we saw a flash of light coming from under the basement door. We searched around to see what caused it, but we couldn't find anything.

From then on I would see the flash regularly at night coming from different windows around my house, especially my bedroom window, but also my backyard and the front door. My brother also saw the flash and he said he even saw it coming from the roof once. The flash was similar to a camera flash, but it was sort of a silver color and extremely bright. I was pretty convinced it was aliens at the time because I sleep on the second floor of the house so someone would have had to be on the roof for the flash to shine through my window at the angle that it did. 

Every time I saw the flash I looked out the window and saw nothing. (It wasn't just a car driving by). This all started in 2011 and continued on and off for roughly 5 months. I have no idea what caused this or why it eventually stopped. I told my parents, but they never saw it and didn't know what to do about it. I always slept with my blinds shut after that.

Me and my friend saw a flash of light randomly illuminate the entire street at night. Years later I went to that place again and summoned UFOs via CE5. AMA.
