Researchers working at MIT have successfully manipulated the content of a rat’s dream by replaying an audio cue that was associated with the previous day’s events, namely running through a maze.
[W]hen the researchers played the audio cues from the experiment, they noticed a very interesting thing: the rats would dream about the section of the maze previously associated with the audio cue.
The experiment demonstrated that the content of a rat’s dream can be biased by re-activating certain memories while they’re asleep.
I am torn between making a snappy comment about potential supervillain origin stories or sly A Nightmare on Elm Street allusions.
