If you’ve ever seen the movie Inception, you’re probably familiar with lucid dreaming. Lucid dreamingis when a person is aware they’re dreaming. It’s a kind of hybrid state between sleeping and being awake. And it looks like scientist found a way to use this state for good purposes.
There are similarities in brain activity between lucid dreaming and psychosis. So basically when you see a dream, you feel the same way as a person who has a psychological disorder would. Sounds weird, right? This knowledge led scientists to conclude that controlling dreams can be very therapeutic.
