Listen to either this hypnosis session or the Binaural Beats version of it at least 3 - 5 times (within a week). After that you may use the HypnoSleep session at any time to embed the learning as you sleep.
This Brainwave Entrainment (BWE) or Frequency Follow Response (FFR) Binaural Beats audio creates a Theta binaural tone. By listening to this audio your brainwaves will synchronise with the Theta binaural beat helping you go deeper into trance.
Due to the nature of binaural beats you DO need to use headphones when listening to the binaural beats version.
