Dream of person

I once had this reoccurring dream that I would have about twice a month. The setting of the dream was in some warehouse or manufacturing factory. In this factory there were belts that were elevated and looked kind of like smooth escalators. No in the dreams I was always challenged to climb these conveyor belts to the top, the trick is they were moving down as I was trying to move up. This wouldn’t be that much of a problem because they didn’t move that fast maybe a little slower than a walking pace, except gravity felt like it was four to five times its natural strength. It took all I had to not collapse to the ground not to mention walking to be super difficult. Now there was not villain or person chasing me but some man always shrouded challenging me to ascend the conveyor belt. I would try and try and try but I have to this day never once made it to the top.
