The concept of time, its nature, and the possibility of reincarnation are subjects of philosophical and spiritual speculation. Different belief systems and theories offer various perspectives on these matters, and opinions may vary.
In the framework you mentioned, where time is not linear and past, present, and future exist simultaneously, the idea of reincarnating into the same year you were born could be plausible. If time is experienced as a whole rather than a linear progression, it would theoretically allow for the possibility of reincarnating into any point within that non-linear time.
However, it's important to note that these ideas exist within the realm of speculation and personal belief. The nature of time and the possibility of reincarnation are not scientifically proven concepts. They fall into the domain of metaphysics and spirituality, and different belief systems may have different interpretations and explanations for these phenomena.
Ultimately, whether or not you believe in reincarnation and the specifics of how it might occur is a personal choice, influenced by your individual worldview, spiritual beliefs, and personal experiences.
