I wish there were more like you who just accepted the idea of psychic or meta-physical abilities as a matter of fact. There have just been too many examples of it over the ages, and many enough in the present time, but it's still largely denied and ridiculed and often by people who have no way of knowing either way.
The way I see it, this is also one of the human potentials that have been suppressed. After all, things like getting access to the Akashic records brings great power, and not many rulers up until now has been in favour of empowering the general public like that. So there's been a distinct lack of real information about something that might be a reality and how it can be trained or developed.
I believe this is mostly a fourth dimensional ability, or a result of being able to access the fourth dimension. So it's mostly a result of the capabilities of your consciousness but I also believe these things have their physical components. Or that some are born with brains, nervous-systems, or DNA which gives them greater potential for these abilities.
A friend of my sister's who's mother has been working on spiritual growth for a long time and now performs healing sessions and past life regressions, etc. for people has now become seemingly completely psychic or can read the "Book of Life" or Akashic records. Meaning she can both see into the spiritual world and the physical world and know things that have happened at any time or at a distance from where she is.
I don't mean I have just taken her word for it, but been exposed to countless examples of it. Like, she knows things about my personal life she should have no way of knowing and can tell me things about my past boyfriends who she's never met, etc. Plus answear all sorts of spiritual questions like how many spirits are presently occupying my aura, though this is harder to proove, but it seems to be consitent with what I've heard from others of the same kind.
I've come across a few like this, and I find them very puzzling, I must admit. Can it be simply a result of "ascending" and getting access to the fourth and fifth dimension? The fifth being more reliable as the fourth dimension is easy to be mislead in. This seems like a privilige for the spiritual elite, but maybe as you say some simply have a better physique for it, like a better devloped part of the brain or something.
