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

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
