Abraham dreamed of a new land, to be solely inhabited by his progeny. I personally don’t believe he heard the voice of God with his ears, but with his mind. Genghis Khan called himself “the scourge of God,” and perhaps he was. Perhaps Julius Caesar was. Alfred dreamed of a United Britannia. Ferdinand and Isabella a United Spain. Columbus dreamt of a quicker passage to the Indies (sometimes we dream of one thing and achieve another.) Benjamin Franklin dreamed up the postal system, among other things. Isaac Newton dreamed of answers, as did Einstein. Chĕ Guevara dreamt of giving power to the people, and probably died believing that he had. Gandhi dreamt of peace, as did John Lennon. Martin Luther King Jr. had a dream.
Please note: I could be wrong—it could have been the wives, lovers, sisters or mothers who had the dreams, and influenced these men to achieve them. Or it could have been completely other people who had the dreams, and they just campaigned for these men to advance their dreams. History has to give credit to some one individual, when almost always the great accomplishments were achieved by a community. Where, though, do the dreams come from? Someone has to be thinking, receiving the flashes of inspiration and bringing the dreams to fruition. Perhaps God or the collective consciousness emanates these ideas into the ether at appropriate moments in time, for the appropriate individual to “come up with it.”
