The present is constant; from the very creation of the material form of the planet Earth and the rest of the universe.
The time of the dinosaurs and the time we know today belong to the same present in which we still live today.
Future ; aging, or changing of matter, happens in sequence for all living and non-living forms of matter. Living matter are the physical bodies of animals, various bacteria and plants, and other dead matter are various elements.
As a result of the commingling of living and dead matter in the future, a by-product is formed and this is antimatter.
Antimatter is formed from all this living and dead matter.
Everything living and dead "occupies space in a vacuum", which also includes the position, where this matter is currently located and in what state of aging it is.
Therefore, in this entire present, which lasts from the very beginning to the present day, i.e. "forever", antimatter intertwines and mixes with each other.
When, after the death of the physical body, individual antimatter comes into contact with its former space in the vacuum, wherever it was, it can momentarily find itself in the dimension in which it lived as a living being.
