Study finds novel evidence that dreams reflect multiple memories, anticipate future events:

Dreams result from a process that often combines fragments of multiple life experiences and anticipates future events, according to novel evidence from a new study.

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. 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. Future-oriented dreams became proportionally more common later in the night.

"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. "We present new evidence that dreams reflect a memory-processing function. Although it has long been known that dreams incorporate fragments of past experience, our data suggest that dreams also anticipate probable future events."

According to Wamsley, the proportional increase of future-oriented dreams later in the night may be driven by temporal proximity to the upcoming events. While these dreams rarely depict future events realistically, the activation and recombination of future-relevant memory fragments may nonetheless serve an adaptive function.

    Anyone else dream about code?

    I do that sometimes, but not often b/c I usually try to separate work from sleep by at least a few hours and throw in something like woodworking and reading to break it up. I do solve a lot of code (more logic, actually) problems while doing something mundane like mowing my lawn.

    I still have dreams about college though, being late for a class, unprepared for an exam, etc. which seems strange b/c I graduated 25 years ago. I do remember dreaming about Calculus though, probably b/c I'd usually go right to bed after working on homework and would wake up in the middle of the night w/ an answer to a problem I couldn't solve at the time. That happened often.

    I've journaled about my [] dreams [] too.

    It's crackers to slip a rozzer the dropsy in snide.

    I had those dreams for about 20 years after college, but they eventually went away.

    Let's not forget the common "showing up to class then discovering you are naked, or somehow very improperly dressed". That probably falls under the anxiety, and 'how would you solve this problem?' type dream.

    What can be done to stop bloggers from using the wrong color schemes?

      The funny thing about those kind of dreams for me is that I seem to be the only one in my dream that notices or cares that I am naked or improperly dressed, so it isn't really an anxiety dream for me. My dreams are really odd, odd things happen, odd situations happen, but it all seems somehow not odd. And the "scene" changes unnoticeably, where I'm in one place, then I'm in a new situation and I never noticed the transition.

      Now: sex dreams. Why can't I have those?
