Samhain

For the Druids, Samhain (celebrated 31st October to 1st November) was the beginning of the year.
As light goes to dark in the northern latitudes,  melatonin levels rise and the pineal - the inner eye or 'seat of the soul' - becomes more active, inner sight becomes more vivid and inner life blossoms.
Traditionally at Samhain time lost all meaning and the past, present, and future were one.
