Several teardrop shaped fading lights, emmited soft sighing sound. It felt like 10 minutes, but lasted 4 hours.I was in my bathroom brushing my teeth, when I heard this soft sighing sound, unlike anything I've ever heard before. I finished, and opened the door to see what it was. The rest of my family was asleep, so I searched around. It sounded as if it was coming from the laundry room, and I went in there and the window was open - it was coming from outside. I put on my slippers and a sweatshirt and opened my door to go outside, and it immediately got louder. I walked across my front yard and into the street and looked up. The sky was blurry in some parts, and it seemed only inches from my face. Then, I saw something move. It would turn on like a bright light, then fade and appear somewhere else. I blinked because I thought I was hallucinating. I watched, and it did it again. Then, I saw that it wasn't just "appearing somewhere else", there were several of these "lights". The sighing got louder and blew through my ears like wind, but I couldn't feel it anywhere except inside my h! ead. It vibrated through my head and was warm; which was strange since the night was cold. Then, as one, the lights faded, and I could feel the warm sighing sound receding from my head. I blinked again, and the sky looked different, as if someone had turned me around and all the stars were backwards. I went back in after what felt like 10 minutes, and was shocked - it was already 2:00am.
