We saw a craft with green and red lights that was flying and had a wobbly (back and forth and left and right) flight pattern.

Me and one other person were outside talking by a fire. We were at the house I grew up at and were talking. Out of the corner of my eye, I noticed a craft in the air out of the corner of my eye. My house frequently has planes fly over it, but this craft was in a location that I hadn’t seen others take. It was coming from the northeast and was traveling south. What caught my eye was that it was not moving very fast for its elevation. I paused our conversation and brought it the attention of my friend. We started looking at it and the craft had red and green lights and was wider than it was long - could have been disk or rectangular shaped. It’s flight pattern was uncommon - it seemed to drift backwards and then pull forwards and it did that as it slowly plodded forward. It seemed far away at first but then as it flew south it took a turn southwest. It went behind a tree and slightly obstructed our view. Once we could see it again the flight pattern headed southwest but the craft seemed to bob up and down. It suddenly accelerated and ultimately disappeared quickly. We were unclear if the craft pierced the clouds or accelerated extremely quickly. It did not seem to make any plane or high pitched drone noise. My friend also got the chills as it flew by, despite it being warm. There was a light rain and there was a full moon.
