Size has realms.
Time is a measurement that'll outlive the universe; however, thoughts are another element completely. Just as mankind watches the universe, the universe watches mankind. Thus, leading to their unknown compromise. That just as humans record their own history and evolve to be independent of the Earth, the universe will house spaces and host its own experiment.
When one's thoughts cross a threshold of potency, it is recorded and brought to life in another dimension completely. To the dismay of this seemingly abiotic realm, only one creature was able to inhabit it. Thenceforth, soon after its first thousand years of circumspection, it wormed its way out through the loose bands of fabric that stitched the realm together, and into the head of a friendly neighborhood dog.
