... but my sense of smell has always been keen to the point of annoying to some folks ("Jebus, Lisa .. how can you smell that ? It's a block away!") so hallucinating doesn't seem feasible.

I wandered from room to room at home to see if anything there smelled like geraniums, or if windows were open, etc ... but then the aroma surrounded me again yesterday at my office and there are no plants, flowers, laundry detergent, potpourri etc around ...
