This is about the parallel universes, there are many hypotheses in physics about parallel universes, since quantum dynamic shows that space have 11 dimensions, and we use only 4, other dimensions are outside of our knowledge. There are many books about 'parallel universes'.

A multiverse (or meta-universe) is the hypothetical set of multiple possible universes (including our universe) that together comprise all of physical reality. The different universes within a multiverse are called parallel universes. The structure of the multiverse, the nature of each universe within it and the relationship between the various constituent universes, depend on the specific multiverse hypothesis considered.

Multiverses have been hypothesized in cosmology, physics, philosophy, theology, and fiction, particularly in science fiction and fantasy. The specific term 'multiverse', which was coined by William James,[citation needed] was popularized by science fiction author Michael Moorcock. In these contexts, parallel universes are also called 'alternate universes', 'quantum universes', 'parallel worlds', or 'alternate realities'.

The possibility of many universes raises various scientific, philosophical, and theological questions.

THE UNIVERSE AND MULTIPLE REALITY
by Professor M. R. Franks

"There is no one reality. Each of us lives in a separate universe. That's not speaking metaphorically. This is the hypothesis of the stark nature of reality suggested by recent developments in quantum physics. Reality in a dynamic universe is non-objective. Consciousness is the only reality."

Unfortunately, most books on parallel universes and quantum cosmology are written in language that an ordinary intelligent person cannot understand.

The Universe and Multiple Reality presents an understandable view of parallel universes and quantum physics––and explains what this means in our daily lives.

The Universe and Multiple Reality explains to the non-scientist reader in understandable, non-mathematical language the paradox of Schrödinger's Cat, the two-slit experiment, and recent developments in quantum physics and cosmology.

There are a great many other books on 'parallel universes', on quantum physics and multiple reality––but none that offers an understandable model of how minds interact with multiple realities at the quantum level to produce palpable physical effects including paranormal phenomena.

I hope this can help your understanding. =)
