Cones of Power

The darker origins of Halloween lie centuries ago as the boundaries between the living and the dead overlapped
No matter what culture it originates from, even modern day celebrations of Halloween reflect its macabre and dark origins.
In modern Ireland, Scotland, Mann and Wales, the festival included mumming and guising, the latter of which goes back at least as far as the 16th century. This involved people going house-to-house in costume (or in disguise), usually reciting verses or songs in exchange for food. It may have come from the Christian custom of souling or it may have a Gaelic folk origin, with the costumes being a means of imitating, or disguising oneself from, the Aos Sí.
In parts of Wales, men went about dressed as fearsome beings called gwrachod. In the late 19th and early 20th century, young people in Glamorgan and Orkney dressed as the opposite gender.
Commercialisation is a more sinister incarnation of the "hallowed evening", and one is more scared at the impish callers that knock the door than any "darkness".
I've often inferred that the humble traffic cone had a more sinister motive for existing. I now realise where I have seen its shape before!
