At my last ever workplace i.e. before I retired, a group of people in a different area to mine decided to decorate for Halloween and went OTT (over the top) with dark and ghoulish props like pretend dead bodies and fake blood etc. It was set up like a murder scene. They were asked to remove a lot of the items because it was not good for workplace morale. I saw the display before it was removed. I realise that they thought it was a clever idea, but it wasn't appropriate for a workplace. Especially a government workplace with strict guidelines on what is or isn't appropriate.

As a result, I interpreted Mrrzy's comment in relation to the possible effect of dark and ghoulish decorations on our psychological state, rather than as potential tools for self harm.

Having said all that, I'm not into Halloween at all. It's mostly viewed here as an unwanted American intrusion into Aussie culture. Sorry!! :-D
