3 people woke up to a loud noise at 3:30AM. We took time to find our glasses. We also took some time to lower the heat. We checked to see if the cats were okay. We looked around briefly to see where the noise was coming from. The sound was nothing that we could attribute to any normal day to day sound, but was most similar to the sound of a hovering camera or something of that sort. Except it was so incredibly loud that we all woke from our sleep because of it. It was so loud and bright that we opened the front door to go outside. Opening the front door, it was obvious that the sound was external because it increased in volume. Stepping out towards the sidewalk, we saw something circular and gun metal hovering. We froze for a second and then panicked and ran inside. Shut and locked the doors. The sound continued for a few more minutes. However, when we returned to the room the clock still said 3:30AM even though so many micro events seemed to have occurred d! uring that time.
