• Elias Howe: The U.S. inventor of the sewing machine, Elias Howe, was struggling to design the needle mechanism. One night, he dreamt of being captured by hostile tribesmen who used spears with holes close to their pointed tips. This dream inspired him to design the sewing machine needle with the hole near the point instead of the blunt end.

• Niels Bohr: The Danish physicist and Nobel Prize winner Niels Bohr is credited for his groundbreaking work in atomic structure and quantum mechanics. Bohr had a dream about a horse race, where the horses seemed to be placed in both continuous and discontinuous orbits around the track. This dream inspired his idea that electrons could only reside in specific orbits around the atom's nucleus.

• Benoît de Maillet: In the early 18th-century, French diplomat and naturalist Benoît de Maillet made notable contributions to earth sciences. Inspired by a dream about his great scientific destiny, he wrote the manuscript "Telliamed," exploring the Earth's history and suggesting it was once underwater. His ideas on subsidence laid the groundwork for future geological research.

• Srinivasa Ramanujan: Indian mathematician Srinivasa Ramanujan, known for his impact on mathematical analysis and number theory, claimed divine inspiration for his ideas through dreams. The Hindu goddess Namagiri Thayar presented him with mathematical formulae in his dreams, resulting in novel discoveries. Ramanujan's intuitive and profound work continues to influence mathematicians today.

• Alfred Russel Wallace: The British naturalist and biologist, who independently conceived the theory of evolution through natural selection, is said to have been inspired by a fever-induced dream. This dream helped him to visualize the process of selection, ultimately leading him to co-present the theory of evolution with Charles Darwin.
