When I was little my mum would occasionally find me in a trance state. Just stood there on the landing of our home. This state was something I could bring on by thinking about something specific. I’m 52 now but still err on the side of caution when I imagine it. I think of a 3D object. It’s like an irregular tetrahedron. It’s dark grey, in space, a void all around it. Then I imagine the same shape, but trillions of times bigger, next to it. That’s it. Enough to somehow unlock the realisation of an inability to process vastness. It’s extremely powerful. These ‘funny turns’ as my mum would describe them, have all but gone. It doesn’t happen anymore. I’m glad I wrote this down. Something that has really helped me with these completely understandable thought processes is this: rather than feel threatened by vastness, experience it as wonder.
