In order to best understand your dream of dying, it is important to look at what is going on in your waking life that may have triggered such a dream.
Bizarrely the dreams were often long periods apart - think the first one was years before the 'death date' but every now and again another dream and always the same 'death date.' Needless to say was a little nervy on the day but went to work as normal. Nothing of any note seemed to happen on that date either to myself or in the world in general. Not had a dream about death since then though which in itself would seem strange.
