It was late at night, I was inside on my bed with a clear view of a near treeline and the sky. I had been looking out into the night sky for a while, when suddenly the dark sky turned bright, not quite white, but like the entire sky was illuminated, and at the center of what I could see was a blurred out sort of shape, which I now believe was the source of the light. At the time it seemed as if it only lasted a second but I am actually unsure since I have no way of confirming the time of when it even began, it could have lasted way longer and I will never know. After it had gone dark again, I can only describe what I felt as shock and I was almost unable to move, I am not sure if it was fear or not. I remember staring at the sky for a long while until I eventually woke up my sister to recount the event to her. I am still not sure what happened exactly but I know it did happen.
