You know what visions I get in my dreams? Visions of falling off of buildings (and doing the full body spasm thing when I hit the ground). These 11 people, on the other hand, had dreams that changed the world.
Let's hope that my visions take a turn toward genius sometime soon. Until then, I'll just take inspiration from these guys.
1. The Periodic Table
It's said that Dmitry Mendeleyev was on a three-day work bender when he finally gave in for a few minutes of shut eye. Instead of falling asleep for 17 hours like most sleep deprived people, Mendeleyev dreamt of an arrangement of elements that would change modern chemistry forever, then popped up about 20 minutes later to record it. "I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper... Only in one place did a correction later seem necessary."
