In Leonardo DiCaprio’s latest movie Inception, characters can enter other people’s dreams – in reality, science isn’t that far behind:
In one experiment, for example, researchers wired up a sleeper and connected him to a robot that was programmed to act out the motions of the dreamer. For example, the robot used data about the dreamer’s eye position to know in which direction to look.
Brain waves can be studied and translated into actions – for example, brain imaging technology can tell whether a person is having a nightmare or dreaming about flying, Barrett said.
