The similarities between Spirits, fairies and aliens described by Graham Hancock reminds us of stories some of us have heard during our childhood, especially the stories of fairies taking children from their bedrooms to fantastic realms where time and space have different laws of physics than what we experience in our 3D physical world called earth. There are many doorways to these realms located all around the earth. One of the most intriguing spots is the Bermuda Triangle located in the North Atlantic Ocean where planes and ships have disappeared or have had some kind of time anomaly.
After years of studying paranormal phenomena I have come to my own conclusion that the key to understanding these altered realities is for one to be in an altered state themselves. There are many ways to achieve this. One way is to ingest natural entheogens such as magic mushrooms, ayahuasca and DMT to name a few. Another way that is increasing in popularity is the use of Binaural beats and Isochronic tones that synchronize both hemispheres of the brain so that each side produces the same brainwaves of which theta and gamma are the key.
