It is not what happens to you, but how you respond to it that defines who you are.
About ten years ago, I was in a cave below Plymouth Hoe at 3am during a storm, began humming, then moved into singing two songs – the first with a repeated chorus, and in perfect harmony with the waves.
Nothing strange there, you might say – except that they were both in a language that I do not know.
I once heard someone speaking Chaucer in medieval english, and at the time thought it useless gibberish.
It seemed as if what I was singing had its roots long before Chaucer – very Merlinesque, in fact.
I am aware of other dimensions ( having experienced them on various levels, including spirit guides ), but after a decade or so, I know no more about this incident.
While I am willing to act as a physical conduit for non-physical beings on occasions, I remain curious about this one, and wonder if in your experience of druidic tradition, you can offer any explanation.
I might add that, in spite of my name, I am of celtic origins, both cornish and scottish.
Someone on UTB uploaded an interview with you, and I was impressed enough to research further.
