The air above the platform shimmered. I half expected to see lightning bolts and bright colored lights but, no, the difference was subtler than that. There was a thickening and discoloration to the atmosphere that made me think of disease and putrefaction. I began to notice a sound, a low continuous moan that seemed to come from no definite direction. As the minutes passed the sound grew more noticeable yet did not seem to grow louder. I found myself breathing more rapidly. With each breath a smell, not of rot as my eyes expected, but of slightly burnt sugar, filtered into my nostrils.
Something moved above the platform. I could not define its shape. It was a thicker discoloration in the polluted looking air. It seemed to be swimming.
