Ill admit that I do feel more tired due to the long sessions but it wasn't tiredness that made me aware of these phenomenon. My best explanation is as the light passes through these air pockets it somehow polarizes the energy around us and reveals it to us in color. Obviously not everyone will see this, you have to be in tune with it to see it, a bit like a lot of other things that you see when you alter the vibrational state of your mind.
To those of you who are new to mind vibrational states let me explain. The brain operates at a frequency depending on what state it is in. These can be picked up as "brain waves" for example someone who is awake on a day to day basis will be in the alpha wave state, someone having dreams will be in the delta state and someone who is stressed or working hard will often be in the beta state. I believe that if we are able to access the states of our mind whilst awake that we can access when we are asleep we can change what we can physically see. For example a Kestrel can see in the ultraviolet spectrum and has different brainwave patterns to us that allows its brain to decipher these images. The human brain is a complex and ingenious device able to be programmed to accomplish amazing feats of calculation. It is much more powerful that your PC an has periferals many times more complex that we only use a small fraction of their capability. If we are correctly programmed we can see, feel and hear things that would otherwise go beyond our senses.
In our world of electronic stimulation is is easy to become desensitized to these subtle energies and abilities. Maybe it is deliberate like some conspiracy theories say, lets face it the government need to be able to lie to you don't they? The last thing they want is a population of people who have special abilities that are not under government control.
Anyway the experiments go on and the things we are experiencing get more bizarre. The full report is a couple of weeks away and I am hoping I'll be able to publish the whole thing here. It may be just a summery, or the whole paper it depends on what is agreed. So keep coming back here for updates. Currently I am listening to Enigma, The 2006 album Valley of dreams. Really good for drifting in and out and chilling to. Also the best of Vangellis
