nextI have written extensively over the years about the process of falling asleep and have sorted my journal into four areas of interest.

Brainwaves and Sleeping

Our big human brains run at various frequencies during the day and evening. For an insomniac such as myself the frequency I strive to curl up with at night is called Delta. This is the brainwave that represents deep sleep.

The average human's (and aren't we all?) brainwaves transition from Beta (alert) to Alpha (relaxed) to Theta (daydreams) to Delta (deep sleep) .

I'm just an insomniac. But having owned a recording studio I do know a thing or two about audio. Let me correct a falsehood that has been propagated over the Internet for years. There is no such thing as an audible Delta sleep tone or sound. Besides the fact that brainwaves are simply not audible sounds*; the average human can only hear 20 Hz (cycles per second) to 20 KHZ. Delta brainwaves are represented through EEG's at 0 to 4 Hz . Theta brainwaves; those relaxing daydreamy signals that briefly occur right before you fall asleep, range from 4 HZ to 7 HZ . Alpha (relaxing) brainwaves occur at 8 to 12 HZ . All are below the human range of hearing. So, if you happen across any sites that tell you they have Alpha, Theta or Delta tones to help you fall asleep fast... walk away.

There is no such thing.

What we strive for here is the natural induction of Theta brainwaves. I know from personal experience that it is this little talked about brain function that is the key to my nightly sleep quest. When you are in Theta you are not really sleeping nor are you awake. You can liken it to that far away feeling one might get as they stare out a window on a rainy day. Theta brainwaves are the bridge to Delta (deep sleep) brainwaves. The theory behind VirtualDreamer.Com is simple. The combination of natural soothing sounds that induce calming Alpha brainwaves with some simple visualization sequences enhances the natural ability to reach the Theta brainwave state. Ergo, sleep soon follows.

But why? Simply, when we 'imagine' we use some of  the same brain functions as when we are dreaming. Specifically this area of the brain is known as the Secondary Visual Cortex and it is active during REM dreaming. In a sense we prime natural sleep mechanisms by lulling the big human brain into thinking it's already sleeping and dreaming.

But what do I know? I'm just an insomniac.

A really, really bad insomniac.

*Some research suggests that Tinnitus sufferers are actually hearing the high frequency sound of their brain's electrical activity that is normally cancelled out by healthy inner/middle ear functions.
