odd fog sightings

so I was standing on my roof earlyer this morning (I have a roof sundeck) I was unaware that it was really foggy and kinda cloudy until I got up there (I was going to watch the sun rise) but in the fog I mannaged to see the outline of a pair of what I thought were buildings that looked quite like the twin towers. (factual note the only buildings that can classify as twin towers are Marina City which is not viewable from my roof) Understandably I was a little creeped out seeing the outline of two bulidings hae no place in the chicago skyline (or truly anywhere ant this piont in time) fit so well.
