What you smell may influence emotions in your dreams, according to a new study. When researchers gave dreaming subjects whiffs of rose scent, the subjects reported rosier dreams. The scent of rotten eggs, on the other hand, provoked unpleasant dreams, the study found.
The different scents were not incorporated literally into a person's dreams, said study author Boris Stuck of the University Hospital Mannheim in Germany.
"There was hardly any kind of a dream dealing with smelling and tasting," he said.
Rather, the pleasant odor appeared to affect the subjects' emotional ratings of their dreams.
