Lateralisation between the hemispheres of the brain is no where near as significant as is often portrayed by those who would tell you you can 'hemi-sync' (usually so they can sell you something)
Lateralization of brain function - Wikipedia, the free encyclopedia
The truth is that throughout your life the hemispheres of your brain work in tandem but interdependently of each other, and statements of 'logical left' and 'creative right' are largely generalisations, remember that each hemisphere is a mirror image of the other with the exact same neuroanatomy on each side.
It would be silly to suggest that your brain would sacrifice half of its processing power for something so intensive as dreaming by shutting down the left hemisphere.
In fact MRI scans show that the two hemispheres show roughly equal activity:
However it is generally accepted in sleep research circles that the higher reasoning centres of the
forebrain responsible for things like operative memory and self-awareness are suppressed.
So if you really are stimulating anything then it would be the forebrain.
Maybe the stimulation of the forebrain becomes associated with the realisation that you are dreaming so that when it finds itself in an inhibited state it triggers the realisation you are dreaming. I which case this technique could hold implications for WILD and recognising the transition without having to remain conscious through the whole WILD. In a way it's similar to the 'third eye' and Nina's technique of WILDing.
However, it may just be a simple matter of mnemonic/auto-suggestion induction, in which case it would be effective as a MILD and may be increased even further in effectiveness if coupled with visualisation.
