We exist in what I visualize as a sort of quantum soup, wherein what we experience as solid matter is actually the binding energies at an extreme end of the electromagnetic spectrum, the opposite end to the more familiar energies such as light and heat. If we were to venture into this end of the spectrum, thoughts would have the same validity or reality as solid matter. The Brooklyn Bridge is real; no one would dispute that. But its design had its inception in thought, didn't it?
