Terry Pratchett said this quote

“ The living often don’t appreciate how complicated the world looks when you are dead, because while death frees the mind from the straitjacket of three dimensions it also cuts it away from Time, which is only another dimension. So while the cat that rubbed up against his invisible legs was undoubtedly the same cat that he had seen a few minutes before, it was also quite clearly a tiny kitten and a fat, half-blind old moggy and every stage in between. All at once. Since it had started off small it looked like a white, catshaped carrot, a description that will have to do until people invent proper four-dimensional adjectives. ”
