Wavelengths of Perception

The human sense of sight is capable of seeinig light in the wavelength range of roughly 400 - 700 nanometers. However, a much broader wavelength range of light actually exists. Some of these wavelengths that are not viewable can still have some effects on the body (i.e. burns). Likewise, the human ears are capable of detecting only a small range of sound wavelengths (usually measured by frequency), and a near infinite range of sound waves also exist.

This leads me to the idea that several "wavelengths" (or levels) of consciousness could possibly exist, however only a small range may be detected by human perception. If this were true, it seems the levels that are perceived may be altered by drugs or while in a dream state.

Taking this idea a step further, one could speculate that an entire range of levels of existence exist, only a small portion of which are able to be percieved within the state of human consciousness. It seems a fitting idea that this perception level is altered while in a lucid dream state.
