Life and our eventual death is f-ing scary. Anything anyone wants to do to help cope with that, no matter how batshit crazy it is to other people, is fine by me (as long as it doesn't hurt anyone else).
If anything, a bunch of inanimate matter suddenly springing up and wreaking havoc is the scary reality. If a bunch of sand on the beach suddenly became conscious and started talking to me, and swallowing people up, that would be far freakier than death itself.
