Wandering through desert alone at dusk

As the title says, i dreamt about wandering through sand dunes and being surrounded by mountains of sand in every direction, there was nothing else just a desert, all of which was around nightfall. I almost never have dreams and if i do, i mostly don't remember them, but this one quite stuck in my mind and i've been thinking about it. I've never been to a desert or somewhere tropical so it's quite strange that i dreamt about being alone in a desert. I felt quite helpless just walking aimlessly. Could this dream have meant anything?
