The team then deployed a machine learning algorithm to analyse the data from the fMRI scans and find patterns that correlate to specific images or dream content. Once the algorithm figured out which brain patterns go with which dream content, it was able to successfully reconstruct the dream imagery based on the fMRI scans. A lot of people swear that lucid dreams are a real thing, that dreams contain valuable information, and that taking control of your dreams can help you take control of your life.
