I know exactly what you mean about Autumn, a warm pumpkin spice drink on a cool windy day with the colourful leaves rustling, or a trip to the local orchard, the crisp air on an overcast noon. And oddly enough it's well written on our website why graveyards in Autumn really do feel so very fitting as you've stated. It doesn't really have a whole lot to do with Halloween itself, but the original holiday
was known as
Samhain "a Celtic word meaning "Summer's End."", it's the season of honouring the dead, perhaps in deep roots of our soul memories we understand our past pagan habits.
Can't say I've gone to a graveyard though since last time I decided to a couple years back, couldn't take the negative energy, was far too open and sensitive to it back then. Might be different now and I can likely more effectively block things out, but I'm still reluctant. I'll stick to artwork and photos of them for now, heh.
Autumn and Halloween are also the season of creativity, changes and bountiful harvests. I very much love the symbology of the coming season, only two weeks from now, and I already see some trees changing colour ever so slightly at the tops. Personally I very much prefer heat and warmth, don't think that has much to do with my own Celtic ancestry though but forests and vast open fields, oh to live in such a free environment in a little stone house.
Some day in the future we'll be able to more personally know one another without having to worry about enemy trickery and garbage... perhaps visitations for holidays even. But damn if that ain't like 4 or 5 whole entire decades of a dream away. It's hopes like that though that keep me holding on and going to save our future and fight for our freedom and immortality.
