Looked out window saw ufo it appeared to fly behind the clouds.followed by two silver orbs 2 right after another then loud engine sound

Friday evening around 9 PM July 14th I looked out my window I am on the 16th floor. There was a UFO outside my window. I can't estimate how far away it was, but it looked like it was at the level of my apartment. It seemed like when I noticed them. They took off. Then I saw. The aircraft began to go behind the clouds. And at that point, it seemed to turn and become the shape of a saucer. Immediately following that, there were 2 orbs. I spotted silver transparent. They were also behind the clouds. Then again, almost immediately standing at my window. I heard a very, very large engine like noise over my head like I said. I'm on the 16th floor and there's only one floor above me. It almost seemed like they were coming after me. I didn't have a good feeling about it.
