Some research has found that the electrical activity of the brain indicates that lucid dreams may involve a mixture of rem sleep and wakefulness. if this research can be repeated, it may point to the idea that it is possible to be self-aware while one is asleep. this finding highlights the importance of
falsifiability
replicability
extraordinary claims
correlation vs. causation

Replicability

Explanation:

Some studies indicate that the brain's electrical activity suggests that a combination of REM sleep and wakefulness can include lucid dreams. If this work can be replicated, the principle that you can be self-aware while you are sleeping may be pointed out. This result emphasizes the importance of replicability
