Summary
AI-generated from the abstractOlfactory stimuli presented during sleep can influence both the content and emotional tone of dreams. Pleasant scents tend to be associated with more positive dream emotions, while unpleasant odors are linked to negative dream content. The findings suggest that external sensory information is processed during sleep and can be integrated into ongoing dream experiences, affecting the emotional quality of dreams.
