I would agree with ooojen on this. I like the fantasy and illusion of realistic looking imaginary. More than the uncomfortable dark feeling of real bones.That's an interesting question!
For me, Halloween is about fantasy and creativity. I'm not in the least creeped out by real human bones, but I would prefer realistic fakes. The real thing is still-- dark, I guess, and so loses a bit of the fun element imo. I realize my take isn't entirely consistent, but I like the concept of it all being illusion. I'd also rather have a realistic-looking thing in a lab jar than have an actual dead animal in a jar. I've had plenty of Zoology and anatomy classes that used dead animals (and some with human or human parts. I'm not squeamish. But that's scientific, rather than fantasy.
Now I just discussed it with DD, and she asked me what about my (real) cow bones. She had me there. I like my cow bones...I know they were the result of natural causes death--- so maybe it is the thought of not knowing the provenance after all. Back to it just being a level of dark that's more than I want.
This is how i feel as well.No, I wouldn't, but that's not really my thing anyway, so it's an easy decision. If I did like to collect things like that, I would probably only purchase an item like human bones if I knew they had some kind of provenance that I agreed with. Like, if a medical school was selling them maybe, or if I knew someone had donated their body to science.
I don't think it stems from superstition as much as for me, it's out of respect - I don't plan to be buried, but if I did, I wouldn't like someone one day selling my bones because years ago some grave robber dug me up or something. I guess people are dead & therefore don't care , but I still care that it used to be a person who maybe wouldn't want to sit on my shelf to be ogled at.
Eh, we're all different. I can understand that people have a fascination or interest in bones, either scientifically, spiritually, or otherwise, but for me, an easy answer of "No, not interested".
