Database: Eivor's Visions

I have no rational explanation as to how Eivor was able to experience visions of Asgard. Clearly, there was something unique about her.

I lean toward science and evidence-based medicine, but every corner of the globe has some version of naturopathy, and many ancient healers used hallucinogens in their rituals and treatments.

We know that precursor people existed, with powerful bloodlines that have been diluted over time. I wonder if there were also Isu plants that had medicinal or hallucinogenic properties that also faded over time? Could ingesting Isu plants have created some kind of organic Animus experience?

Were there Isu hippies back in the day, just tripping out on their own genetic memories?
