It was a bright and sunny day during April- May(can say, peak of summer) in a country in the northern hemisphere, near to the equator.
I was wandering(on foot) through this country's vast and open land - harsh desert - and in the evening seen a strange thing - the sun was setting in the East - for a while.
I am pretty sure about the directions and I was not mistaken.
How was this possible / it can be explained?
