What Graham Hancock Shows Us Here Is Not it Any Book Ever Written

Many people who have experimented with psychedelics have at one time or another had the experience of encounters with what appear to be intelligent, non-physical and non-human entities and very frequently these entities appear to communicate with us telepathically, and even to teach us useful knowledge. Are these entities, which bear close and surprising similarities to modern notions of encounters with ‘aliens’ and ‘ET’s’ just figments of “our brains on drugs” mere “hallucinations” with no reality to them or is there something else, much more mysterious and much more significant going on?. or is it that humans beings as a species are social beings and as such we all just love a good party, or maybe just maybe its a bit of both ;)
