High Tech Dreams – Have Computers Gone Too Far?

Computers Can ‘See’ People’s Dreams

Editor’s Note | Higher Journeys

For good or bad, technology has essentially managed to seep its way into most aspects of our lives. And although the choice is still largely ours as to what degree we allow computers to partner with us, there are some areas of privacy that need to remain, well, private.

Although I’m certainly not adverse to discovering new methods to understand the workings of the brain, I wonder if the following article is alluding to the idea that one day soon our computers will be reading our every thought? Or are they already?

Nonetheless this article, originally published in 2013 gives some astounding insights into how the dreamscape is now being explored.

A computer can predict what you’re dreaming about based on brain wave activity, new research suggests.

By measuring people’s brain activity during waking moments, researchers were able to pick out the signatures of specific dream imagery — such as keys or a bed — while the dreamer was asleep.

“We know almost nothing about the function of dreaming,” said study co-author Masako Tamaki, a neuroscientist at Brown University. “Using this method, we might be able to know more about the function of dreaming.”

The findings, which were published today (April 4) in the journal Science, could also help scientists understand what goes on in the brain when people have nightmares.

Sleepy mystery

Exactly why people dream is a mystery. Whereas the founder of psychoanalysis Sigmund Freud may have thought dreams were about wish fulfillment, others believe dreams are irrelevant byproducts of the sleep cycle. And yet another theory holds that dreams allow the mind to continue working on puzzles faced during the day. In general, most people believe their dreams have meaning.

Scientists have dreamt of being able to look inside the brain’s sleepy wonderland. Past studies had suggested that people’s brain activity can be decoded to reveal what they are thinking about: For instance, scientists have decoded movie clips from brain waves.

Dream reading

So why not try to read dreams?

Tamaki and her colleagues tracked brain activity using functional magnetic resonance imaging (fMRI) of three people as they were sleeping; the researchers woke up the trio every few minutes to have them describe their dreams. In total, the scientists collected about 200 visual images. [7 Mind-Bending Facts About Dreams]

The researchers then tied the dream content that participants described in their waking moments to specific patterns in brain activity (as seen in the blood flow in fMRI scans) and had a computer model learn those signatures.

The computer model then analyzed each person’s dreams. The model was able to pick out the time when each person dreamed of specific objects based on their brain activity when they were awake.

Those findings showed the same brain regions are activated when people are awake as when they are actually having the associated dream.

“We were amazed,” Tamaki said.

Even though the team just tried to read dream imagery from one person’s waking brain activity, they found some common patterns for broad classes of imagery, such as scenery versus people, Tamaki told LiveScience.

“There is a similarity amongst the subjects, so from that result, we could pick up some basic dream content and then we can build a model from those base contents, and they may apply to other people,” Tamaki said.
