Time travel is, for those that know how to do it. I know people that have met older versions of themselves.

This is from a Jodie Helm channeling: "The availability of time travel depends upon the dimension where one resides and whether or not it operates in circular time. If a being has physical form and knows how to use the gateways, they can travel to different times, realms, and dimensions. If these gateways and how to use them are unknown, the physical body cannot cross over to other realms or dimensions, however the soul, consciousness, subconscious — all similar aspects of a person that overlap — can still access other places and dimensions in a non-physical capacity. Some people access these during the dream state, meditation, trance state, and astral travel. Again, these things overlap in meaning and effect." https://jodieshelm.medium.com/multiverse-simulation-and-quantum-stuff-edba24c1d134

Here's something I came up with myself to wrap my logical head around this being my 17,043rd human incarnation in what science says is the 300,000 year history of our species: "As relating to time, I believe that souls are time travelers in that we can choose to improv-script our masterclasses at any point in time. I do not believe an already-lived-life has to have taken place in the past nor that a yet-to-be-lived life has to take place in the future. I do not believe that the paradoxes of time-line crossing as discussed in science fiction present an issue. Each chosen setting is an alternate reality."

That's from my https://medium.com/know-thyself-heal-thyself/cosmic-strings-of-time-526824bdd58c. Of course, science could simply have the time frame of homo sapiens wrong. Or maybe I had lots of lives as earlier human forms. I don't think so but 🤷
