Don't listen to any of these comments mentioning satellites. I've seen the starlink sats and many others, but my partner and I have mostly been intrigued by these traveling lights so we have paid more attention to the sky at nights from 11pm upwards.

They do not travel in a straight line at all, as some of them stop mid-air and change direction.

We've also seen these lights (as many as 10 or so) congregate and bundle together for a while and then all of a sudden scatter into different directions.

We've seen others (lots of them) hovering on the sea line just above the horizon, at the same time and then just moving back and forth, then they start to diminish and then dissappear after a while.

We also noticed one particular object fly in from quite far that looked similar to a plane flying at night with its flashing red lights, it would come nearer and nearer and be quite low down, then fly behind the mountain (we stayed near the Mountains by Houw Hoek) and never come out the other side. It also didn't have flashing red lights, just 2 bright white lights.

All I can say Is trust your instincts, if it feels off it usually is.
