Inception is the cinematic blockbuster from writer/director Christopher Nolan about the power of dream states. I've been waiting a long time to see this finished project, having read about it years ago.
Essentially, the movie is a psychological thriller about the intricacies of the psyche, especially the Alpha state of the subconscious mind. Dreams are validated as real experiences, holding secrets, meaning and power if we can bring them into awareness.
The movie's star, Leonardo DiCaprio, said he prepared for the role by reading Sigmund Freud's "Interpretation of Dreams". Oh, Leo, you could've called me to help you. I would've let you borrow my Interpretation of Dreams collector edition. . . maybe do a session or two on the couch.
Brain Wave States
There are four brain wave states that take our mind to different places. First is Beta wave, where we are awake, alert and oriented to all things. Our mind is active and in a conscious state.
The second is Alpha wave, where we are relaxed, perhaps daydreaming, cat napping, meditating or enjoying a blissful calm. We are not asleep, but we are barely there. Our minds dimly register what's currently going on - and have greater access to subconscious thoughts.
The third is Theta wave, where we become drowsy and fall into light sleep.
Deep sleep is Delta Wave, where we are out for the count. The movement between Delta and Theta waves is the zone where we dream, and where REM sleep can be measured.
If you want to develop your mind to access subconscious thoughts, sharpen your Alpha waves by meditating, daydreaming or taking a cat nap and see where things take you.
Note: Thanks to Xmichra for reminding me that Alpha waves, which spur subconscious thoughts, can also cause triggers.
