Interesting Zacs......
I have seen many a patient die of cancer and in their final days, they seem to develop a state of euphoria which could be described as a "hypnotic state."
it has been suggested that in the terminal state of cancer, the tumour produces an endorphin type of substance which promotes a "peaceful end" but i think that the scientific evidence for this is "sparse."
Personally i would rather have a good slug of Brompton's Mixture, than be hypnotoised.
