Meanderings and ruminations

I began to think of a state of mind, and wonder if it is a small chunk of universal mind, or is it all my own. Does it choose my dreams, or leave that to the unconscious? I'm thinking this is what time travel is all about, and before one returns to his home reality, has he indeed left his body? Has he crossed dimensions? What is the stimulus for separating realities? Is there a parallel between this, and what he can do when he leaves his physical lifetime, and becomes spirit alone? Here are my thoughts breeding questions...breeding a lesson in patience. The answers will come, and along with them, more questions. It makes one contemplate his death with the stirrings of appetite.
