Our brains have different sets of waves that correlate to different sets of being.Deeper brain waves can enhance creative ideas. They can help you solve problems through seeing imagery or having spouts of inspiration.

The brainwaves are:

1.Beta
2.Alpha
3.Delta
4.Theta
5.Gamma

Researchers have found an association between the brainwave network structure and physiologic states(Liu, Bartsch, Mantegna, &Ivanov, 2015) . Particularly, that we transition from one physiologic state to another through going through a pattern of reorganization that is activated by brain rhythms. Additionally, words that are heard can affect our deceleration of the heart, even words that are uttered by a computer and not a person. 

So what is it like when you start to enter into the deeper brain wave states?

If you haven’t had any practice with it, it feels like the feeling you get just before you fall asleep.  And, if you are a light sleeper by listening to recordings of Delta or Theta you may go straight to sleep. It becomes harder to stay awake once you get to these trance states as you become so relaxed.

What value would Delta or Theta brain states bring?

You could say that these deeper states are locations where you can install newer belief sets or reprocess emotional turmoil so that you are better able to handle emotion. The Beta state is obviously incredibly useful because it is what we use when we think logically. We need it to solve problems. Most of us don’t really know how to consciously manipulate our motivations, fears or access areas where we can be incredibly creative. The Delta and Theta states can accomplish this.
