The belief you mentioned, where our souls constantly go to a parallel universe that continues our life as this one ends, is an interesting and imaginative concept. It aligns with certain ideas found in speculative fiction, multiverse theories, and even some spiritual or metaphysical interpretations.
In science fiction and multiverse theories, parallel universes are hypothetical realities that exist alongside our own, each with its own unique set of events and possibilities. Some variations of these theories suggest that when we make choices in our lives, the universe splits into multiple branches, each representing a different outcome. In this context, your belief could be seen as a variation of these ideas applied to the afterlife.
From a spiritual or metaphysical perspective, some belief systems entertain the idea of souls traversing different planes or dimensions after death. This notion is often linked to reincarnation or the concept that consciousness exists beyond the physical body.
It's important to recognize that beliefs about the afterlife are deeply personal and can vary significantly from person to person. They are often influenced by cultural, religious, philosophical, and personal factors. While beliefs about the afterlife cannot be definitively proven or disproven, they play a significant role in how individuals find meaning, cope with mortality, and understand the nature of existence.
Ultimately, whether your belief aligns with certain scientific theories or not, what matters most is that it holds significance for you and provides comfort or insight in your exploration of life's mysteries.
