When it comes to the human brain, the truth is, we don’t really know much about it. We just know that it helps us think and successfully stores a vast amount of information. Outside of those everyday functions, our brains do things that you might not know about. Here are some of the many weird and amazing functions of the human brain.

And Over Again

Déjà vu has been an oft-discussed phenomenon for years.

“Lucid Dreams” isn’t just a popular Juice Wrld song or an influence on the film Inception. These sorts of dreams have been researched since the ’60s. In a lucid dream, you control everything that happens. Lucid dreams can become so intense that contests are even being held for the best one.
