On an ordinary level, you are in this world with a separated body, which at any moment could be severely damaged or die, and a life full of limits. At the same time, you are in an unlimited universe. While our world has measurable limits, it is not possible to measure the universe in which we live. To complicate matters, science, with the theory of the multiverse, first proposed by Hugh Everett III in 1957, argues that there are other universes besides ours, just as unlimited. Science also adds that what you are and do in this life expresses itself differently in parallel universes. In these realities, all possible variants of yourself and of others exist. All the choices you don’t make in this reality are made in alternative universes. How to contact these universes? Maybe it’s not about going too far. The key to navigating other universes lies in the imagination and dreams. Every day you imagine and dream, then you return to the official reality, that of this world. But are you certain that this is the actual reality? Imagination and dreams could be other realities, which you have chosen to ignore to give space to a single form of imagination and dream, that of this world. Considering it as the only reality is the most primitive level of awareness from a mystical, spiritual and multidimensional perspective, and also from a strictly scientific point of view.
