The smells that our nose perceives while we sleep condition the content of our dreams , according to a new German study presented yesterday at the Annual Meeting of the American Academy of Otolaryngology, in Chicago. To reach this conclusion, Boris A. Stuck and his team conducted an experiment in which they exposed a series of subjects to pleasant (pink) and unpleasant (rotten eggs) smells while they slept.

Stuck assures that the results could serve as a starter to develop aromatic night therapies that enhance our rest.
