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."
