Well we know Nightmare Night is the Equestrian Counterpart to the human Halloween.
Today Halloween is mostly surpressed by Companys and Supermarkets, who start to sell Xmas Stuff as soon the Calendar hits the 1st of September (2 Months before Halloween and nearly 4 Months before Xmas).
I think the Countrys realy should set an Rule, where Shops are only allowed to sell Xmas Stuff from 1st of November.
I know People like to buy Stuff in Advance, but nearly 4 Months before Xmas is way to early, I mean for some it is still Summer.

So I came up with the Idea how it could affect Nightmare Night if this would be similar in Equestria.
Maybe the well know Movie “The Night before Christmas” is a bit in that Direction too.^^
We not have much of Halloween here in Germany, maybe because we already have an own Version with St. Martin at 10th/11th of November.
But I also have see a Documentation about Americas Halloween, how it is not longer celebrated in some Areas, where People not longer Decorate and the few who want to celebrate Halloween get nearly no Visitors after Corona has endet.
Well I hope this Tradition will not die out and I also hope this Picture is ok for the Event and also reming at that Problem we have in many Countrys.
