Even cremation, common though it is, weirds me out. I won't make any claims to it being a rational thought process, either. Dead is dead. But there's something about eliminating the form of the body that just makes me feel unwell. I didn't even know I would feel that way until years ago when my little brother passed away and was then cremated. The moment I found out he had been cremated was more emotional than I'd have thought. It wasn't quite as bad when my mom recently died and was also cremated, I knew what to expect, but still. I occasionally go to my father's grave (not cremated) and feel as if I can talk to him. No such delusion is possible when I go to my mom's grave site.
I'm weird. No denying that.
