This sounds just like what the guys told Rita and me 15+ years ago, that we never lose memories, we lose access to them. Only, TGU said the memories are stored in the non-physical (which is why they are invulnerable to physical injury). Physical injury can prevent us from accessing them, but when we go over to the other side — the non-3D, they’re still there as they were all along. Little by little, science catches up, sometimes.

Sounds so like storing things on the cloud. Nothing is ever really lost.
My suspicion is that the Akashic record IS the fabric of time-space, and therefore it’s hard to see how anything could be lost.
After being in a coma with brain damage. I had no access to my memories in the non physical,( ie the Akashic Records or the Book of Life), but as my brain healed most of my memories returned.
