I have a fear of just one day gravity will just stop and we all just fall upwards into space. It's a legitimate fear I have and I've normalized it in a way that everytime I'm anywhere outside I immediately look around me to find something I could stand under to catch me if it where to ever happen. I lay down on the ground to look at the sky but I just can't look too long before I start getting a lil scared and I just start closing my eyes. Just the other day I was getting the fear in my car while I was on the passenger seat while my older brother drove just "Holy **** what if it just happens right now f***" and I was getting so scared once I went to my room I knew if it happened there I could just land on my ceiling. Idk maybe I'm just weird but it's a fear I've had since I elementary.
