Look at the dimensions as all different floors of a building and past/present/future lives as rooms on each of the floors. Some take place in the higher floors and some on the lower. You don't need to spend so much time trying to understand the dynamics of it. Focus more on feeling the experience of it. What is the temperature, the vibration, the colors, the light? How does each floor feel to you? This is where you will find what you are looking for.
