People have always asked me what does Theta mean? On this web site, I will be referring to the brain wave “THETA”.  There are other meanings for Theta.  

Here are a few of other meanings:

  • Mathematics – represents plane angle in geometry
  • Greek Letter – it is the eighth letter in the Greek Alphabet
  • There is a symbol of a circle with a plus sign inside, it was called theta and was meant for the symbol “Earth”
  • and more


  • Theta brain waves, measured at 4-7 Hz, are the brain state of REM sleep (dreams), hypnosis, lucid dreaming, and the barely conscious state just before sleeping and just after waking. Theta is the border between the conscious and the subconscious world, and by learning to use a conscious, waking Theta brain wave we can access and influence the powerful subconscious part of ourselves that is normally inaccessible to our waking minds. While in the Theta state, the mind is capable of deep and profound learning, healing, and growth – it is the brain wave where our minds can connect to the Divine and manifest changes in the material world.  (Phillips, 2006)
