In regard to the term 'silly' in the piece on Silbury Hill, it is not always well known that the term 'giddy' stems from an Germanic Root *gudigaz which means 'Possessed by a God'. This is something that happens to individuals who are 'Possessed by a God'. Also, the word 'hallucination' is said to mean 'error', 'delusion', or 'perception of things that do not exist'. However, if you look up the same word up in a dictionary of around 100 years ago it means 'wandering of the mind'. This meaning is totally different, and shows how our word-hoard has been distorted. It is most likely that 'hallucination' comes from the IE Root *alu- meaning 'to put under a magical spell'.
