I hate to break it to people, but this universe is the one where people occasionally eat spiders.

I remember a certain episode of batman beyond as a kid giving me a strange fear of “using powers to phase through walls and ending up accidentally falling through the ground”. On second thought though, thats the least of your concerns; you wont actually hit the ground or anything and more importantly you’ll phase through the air molecules as well instead of breathing them
