Sweet smells, sweet dreams

Researchers in Germany looked into the links between smells and people's dreams. They exposed people who were asleep to the smells of rotten eggs or roses and then asked them about their dreams when they were woken up. Those who had been exposed to the pleasant smell were more likely to have had pleasant dreams, while those who had been exposed to the rotten eggs were more likely to have had unpleasant ones.
