Strange Occurrences on Campus

During a late-night conversation in the dormitory, my roommates and I discussed the eerie rumors that had long circulated throughout our school. Legend spoke of a mysterious phenomenon in the stairwell connecting the third and fourth floors of the academic building, where a door would occasionally materialize out of thin air. No one knew what lay hidden behind it. Spurred by curiosity, I suggested that we investigate the door together the next time it appeared. However, when we finally located the elusive entrance, we realized too late that some mysteries are never meant to be explored.
