'This is a new description of how dreams draw simultaneously from multiple waking-life sources, utilizing fragments of past experience to construct novel scenarios anticipating future events,' said Wamsley.Īccording to Wamsley, the proportional increase of future-oriented dreams later in the night may be driven by temporal proximity to the upcoming events. The following morning, participants identified and described waking life sources for each dream reported the previous evening. During the night, participants were awakened up to 13 times to report on their experiences during sleep onset, REM sleep, and non-REM sleep. The study involved 48 students who spent the night in the laboratory for overnight sleep evaluation using polysomnography. Although it has long been known that dreams incorporate fragments of past experience, our data suggest that dreams also anticipate probable future events.' 'We present new evidence that dreams reflect a memory-processing function. 'Humans have struggled to understand the meaning of dreams for millennia,' said principal investigator Erin Wamsley, who has a doctorate in cognitive neuroscience and is an associate professor in the department of psychology and program in neuroscience at Furman University in Greenville, South Carolina. Future-oriented dreams became proportionally more common later in the night.

The study also found that 25.7% of dreams were related to specific impending events, and 37.4% of dreams with a future event source were additionally related to one or more specific memories of past experiences. Results show that 53.5% of dreams were traced to a memory, and nearly 50% of reports with a memory source were connected to multiple past experiences.

Are dreams similar to creating memories
