Time travel, but not as we know it.
The human body is a time machine.
Acts as a corporeal conveyance for a spectral soul, which exists (largely) as energy in a spectrum beyond the time continuum.
A collective energy, dividing, then existing as a singular cell, within a cellular, nodal framework, an interconnected, distributed networked configuration, within which each cell divides and then seeks to become collective.
Experiencing what we understand as linear time from the moment of conception, through to the moment of death, then returning to the collective.
In this model, time travel is simply the act of having a corporeal form that inhabits a physical, dimensional reality. Think of this as like a dolphin that largely exists within the three dimensional body of water, then for a short time, leaps into the air as a celebration of life, then returns to ocean. Corporeality is bound by a set of rules that applies only to the physical dimensionality and causality that we understand as human experience. Yet, there are other experiences.
...consider the cellular aspect of neural networks of the human brain.
Memories are charged to long to memory, through emotional influence of a day, in the moments prior to sleep. During the sleep process, the human brain will access emotional memory of that day, in order to defragment and optimize storage through biochemical imprinting. Mapping neural pathways to that memory. If you have constantly thought about this thought, the brain will prioritise that thought into memory. If the incident caused a limbic response in the amygdala (flight or fight), this memory will be imprinted into long term memory as an act of self preservation, for the purpose of avoiding similar future instances. However, when this memory is triggered, the neural pathways will re-ignite the limbic system, triggering the amygdala response.
In this biochemical way, the human body and the brain, can not easily differentiate between past, present and future. Instead, neurology ignores time and space, preferring to treat past incidents as if they are happening in real time now.
Despite the fact that a memory relates to the past, the limbic response to a memory is that this thought is happening right now. So in a round about way, we live beyond space and time, through the fundamentals of our neurology. This goes deeper. Because genetic memory also carries coded genetic memory that has causative affects on present time behaviour.
