Hello! This was taken roughly 8:30 pm in Hamilton new Jersey.  My dog was barking to go outside, I had taken her outside and heard this vibration noise, I felt that in my chest as well before I even seen it. What started as a white or but turned into a small but big craft. It started off with a sound I have never heard before sounded like a sci-fi movie and then turned into a slight helicopter noise, I'm so confused as to what this is we have helicopters that go over sometimes 3x a day and it never sounds likes this!!
