I remember watching a programme once about the nature of our reality and im no scientist here but it kinda concluded that our reality is like a hologram. There were also a bunch of scientific tests where they were doing stuff with atoms and they basically behaved differently when they were being 'watched' I found this all very fascinating. Like what would reality even look like at an atomic level, quite tippy I'd imagine! Did u really dream of a unicorn or Was that just an example either way, I would love one to visit me in my dreams very beautiful and symbolic.
