Very interesting, a woman suffered a stroke which stopped her from dreaming (yes, evidence that certain people cannot actually dream) yet she continued to have REM sleep, and through investigative studies, scientists have found out which part of the brain causes dreams.
This is great for new research, perhaps giving us an answer as to why we dream, and in time maybe even the ability to record them. Great news, this.
