Bedroom scents could affect dreams

Researchers in Germany conducted a test on 15 healthy young women while they slept. When the women entered REM sleep the researchers woke them and asked what was on their minds just before waking.

The women reported more positive dreams when they had smelled a rose scent during sleep and more negative dreams when they had smelled the scent of rotten eggs. The type of scent did not affect how long the dreams lasted or how bizarre the dreams were.

The findings were presented Monday in Chicago at the annual meeting of the American Academy of Otolaryngology.
