I’m sure it is, hello Xetrov!
Yes, I mean the noise you hear in total silence. As far as I know, hearing this noise all the time is very good sign. It marks high energy levels of the CNS as long, of course, as it’s not pathological (tinnitus). This noise seems to be the aural equivalent of entopic lights, the undulating light patterns we see with closed eyes. One definately needs earplugs to fully observe this noise. Not using earplugs could be the reason why this phenomena escaped so many folks notice.
My first observation was that the noise is especially strong after interrupting sleep. It also shows up a flutter like quality that reminds me sort of an internal instability. It actually marks my increased ability for changing brain arousal at will.
Usually I use the noises to focus my mind on while I count myself into internal silence (which is this noise actually, lol). Absorbing my attention within this noise is the best way I know for getting silent. Thee noises seem to empower suggestions too if you regard a perceivable set of them as a projected part of my self which then I can communicate with. Like houndreds of radios left on at once.
I’ve also found that hypnagogic noises (music, voices, etc.) are more inklined to burst out from this noise background when they have this instability. To a certain extent I’m able to envoke hypnagogic noises by, so to speak, getting out of their way and letting them to burst out on their own.
And of course, as many of us, just before I WILD I tend to hear rusing noises. In my case they are accompained by strong pressures and pulsating noises that build upon my temples and/or the centre of my head. Someone pointed out it’s similar to vomiting and I’d said I’m very pleased with this conceit.
This is the way, too, at least for me, how paralyis should be induced, that is, by getting out of the way of pressures and lettinng them to break into my mind as strong rushing noises.
After binaural exposition the internal noises seem to be empowered too, supporting my belief that the noise generating circuits are closely associated with the arousal level regulating system. It was a quite promising news for me at that time but so far I was unable to use the noise as a stand alone trance progressor feedback signal, though I’m sure it’s possible.
Since then I read a couple of articles in the field of sleep physiology that deal with this noise. Most of my hypothesises were confirmed. For example, beside the connection with the brain’s arousal regulating system (in strong association with the homeostatic process) I mentioned above, evidences for distinct EEG subbands in the mid and high alpha are found that indicates the actual state of the circadian process. This somewhat explains why I’m able to estimate my chances for success by carefully sampling the noise before I attempt WILD.
Apparently these noises are great for inducing temporal lobe transients (TLTs), which are, according to Persinger, strongly associated with religious and OBE-like experiences. It is said too, in yogic circles, that one should concentrate only the sounds coming from the right side. This is quite congruent with the latest research in the field (angular gyrus, etc.) and the possible role of right temporal and parietal lobe structures in the OBE-genesis.
I’ve practiced anahatha yoga, well sort of. According to the yogis, the “unstruck sound” emanates directly from the Source. They distinguish 10 different type of anahatha sounds revealing themselves in a progressive manner when one use these noises as an object of concentration. Eventually leading to the the higher planes this method is preferred for astral travelling.
It is said too that the base and anahatha chakras are connected to the noise which I found to be true and consistent with my theories (base chakra as body projections of brainstem’s pacemaker neurons and anahatha chakra as projection of the thalamus responsible for sleep spindle genesis and closure of the sensory gate, detachment of the dream body). Headstands, which I’m a great fan of, works too.
Some yogis concentrate on a fist sized, oval structure in the upper rear part of the head. It’s called bindu and also mentioned as a one of the possible sound source yet I failed to confirm this. My noises come from the center of my head, however, in the later stages of relaxation I like to project and merge them with bodily vibrations to form the unified mind-body state of trance.
Well this is in nutshell I can remember at this moment. Hopefully I was not too technical but I wanted to put some strong points on the usefulness of these internal sounds.
Or you could focus on HI but then you are more likely to fall asleep and not get a LD. You could try focusing on counting for a few weeks and if that doesn’t work, try switching over to watching HI.
I’ve never been able to get past the vibrations when going to sleep at night but if it happens in the morning I almost always WILD very easy and fast
