The left brain is logic, science, analytical and so on.
The right brain is artistic, musical, emotional, long term memory and so forth.
They communicate through the Corpus Collosum which is a barrier between the two. There are millions of connections through this barrier, but they rarely are really active for any time.
But fMRI technology proves that when we enter hypnosis, those connections come alive!
When that happens, serious communication starts to flow both ways. All of a sudden, we have both sides freely sharing with one another and this opens possibilities we do not normally have available to us.
