Sleeping, Dreaming, Waking

In Quantum Theory, the world exists at once and not at all, everywhere and pending still. 

Probably the best-known example of the Uncertainty Principle as it relates to Quantum Theory is that of Schrödinger's cat. In the example, a cat is imagined as being enclosed in a box with a radioactive source and a poison that will be released when the source (unpredictably) emits radiation, the cat being considered to be simultaneously both dead and alive until the box is opened and the cat observed. 

In the Quantum world, we imagine ourselves to be, and it is so.
