Has it ever occurred to you that your mind has in store more than you could imagine?Just think about all the phenomena that appear in your mind without you willing them there.Take dreams as an example. You don't command them into being, yet your dreams emerge from somewhere. Memories act the same way. You're in the kitchen preparing soup and remember a day from childhood when your family was eating steak. You didn't summon that memory. It showed up on its own. Other types of thoughts also turn up without help. You're sitting in traffic when the answer to a computer problem hits you. How did that happen? You weren't thinking about the computer problem, but your mind created the thought and somehow pushed it into existence. Those dreams, memories, and thoughts didn't come from outside of you. You generated them through means hidden from you.
