I have a human scull in my bedroom. It’s s actually in a wooden box that was made for it. I bought it as a student for studying anatomy before the regulations were introduced re body parts and now can’t dispose of it without mega red tape. So it sits in its box on top of the wardrobe.
I’d actually forgotten about it until I saw your post.
It used to live under the bed until my DS, then a 2yr old, found it. We were having a lazy morning in bed waiting for the bin men ( his favourite day when he would watch them empty the bins and wave to them out of the window). He disappeared under the bed then appeared looking about a foot taller. He was chatting away and told me he was standing on the man’s head. It took me a little while to work out whose head he was standing on but quite impressed that at 2 he identified it as a man’s skeletal head.
It then got moved to the wardrobe, out of reach. I have considered making it a feature but I no longer have the receipt for it so could be tricky to explain where I acquired it.
