Brainwave entrainment is fascinating stuff. I've just begun experimenting with it and have gotten some interesting results. I use an audio visual system combined with cranio-electric stimulation, and when I first turned the mamajamma on I nearly went into shock from the sensory overload, so I backed off the intensity a bit and relaxed into it. After the session (7.8 Hz, the frequency at which electromagnetic currents propagate around the earth, or Schumann Resonance) I felt very calm and clear-headed. I had a slight headache, more annoying than painful, that seemed to be originating from my corpus callosum (the transverse nerve fibers connecting the hemispheres of the brain), and I slept that night for a solid thirteen hours. The headache I attribute to my brain being thrown into hemispheric synchronization at such a speed, and the sleep was necessary for the unprecedented neural connections to be formed, or at the very least, processed. I'd be very interested to hear of some of your experiences with this technology. Maybe we can compare notes. Best regards, and welcome to Suicide Girls.
My set up is the DAVID Paradise XL +, and no, I'm not a shill for the company. This model combines low intensity electrical stimulation via electrodes attached to the mastoid process behind each ear with visual processing field-specific lights and either a pulsed, binaural tone or white noise, whichever is preferred. It is a bit overwhelming at first, and both of your points on this matter are valid. It's better to begin with simply low volume audio entrainment, but for the intrepid (or balls-out reckless) the combination of different stimulations can produce some interesting subjective experiences. However, it's best to go slow with anything that alters something so fundamental to a person as their brainwave patterns. Base brainwave patterns are highly variable from person to person -- albeit within a limited spectrum -- and an entrainment that's relaxing to one person may be highly detrimental to the mental or emotional health of another. A "normal" person vs. a person with a bipolar disorder, for instance. Much research to be done.
Regarding remote viewing, I've read a bit on the subject myself and it seems to me that unless a person were both experienced in the technique of RV and knew his/her mind well enough to know which flavor of subjective state would best facilitate the experience, they would only be distracted by entrainment. However, if both of the above conditions were met, the possibility of a startlingly accurate session would be great. The mind is a wonderful, powerful thing, and I've only begun to scratch the cortex.
Have fun in Portland, I hear good things about that city. I hope to get out there soon myself, I haven't traveled enough in the Pacific northwest yet. Until next time, keep your feet on the ground and your head in the clouds. Nootch.
