Rei's vision may be brought on by contact with the resident soul of Eva-01, Yui Ikari. At the end of the vision Rei looks up from within Eva-01 and is patently shocked, letting out a gasp.
Interpretation
"Mountain... Heavy mountains. Things that change over time. 山。重い山。時間をかけて変わる物。
Sky... Blue sky. What your eyes can't see. What your eyes can see. 空。青い空。目に見えない物。目に見える物"
Rei compares Mountain and Sky, these are other terms for earth and heaven, terrestrial and the celestial, body and soul. One is visible to the eyes and the other isn't. Rei alludes to physicality's transience …show more content…
A human creation. エヴァ。人の作りした物。
What is a human? A creation of God? 人は何?神様が作り出した物者?
Is man a human creation? 人は人が作り出した物者?"
"Man made from red soil" to "Is man a human creation?" may describe a six-fold process of progressive creation that is akin to the Lesser Countenance, making "the woman who never bleeds" Aima.
"The things I possess are a life and soul. I am a vessel for a soul. 私にある物は命、心、心の入れ物"
Following on from the above interpretation the vessel is allotted onto Kingdom, where the soul intersects the vessel.
Entry plug, the throne for a soul. エントリー?プラグ、それは魂の座。
The Entry Plugs act as a throne for the soul of the Lilim as the Evangelions are the highest forms of life on the planet besides Adam and Lilith.
Throne of the soul, or the seat of the soul, is a term Descartes coined to describe the pineal gland which he believed to be the place where the soul intersects the body. In more modern New Age thought the pineal gland is usually said to be the manifestation of the anja chakra, also known as the third eye or mind's eye.

Who is this? This is me. これは誰?これは私。
"Who is this who is thinking these thoughts?" I think therefore I am, Rei says to herself, yet Rei is not satisfied with this answer and goes on to ask more …show more content…
目に見える私。でも私は私で無い感じ。
Rei recognises her previous mistake and that the visible "this object is me" isn't her self, and that there's something beyond it, which is her unseen soul. Rei peers past the veil:
Very strange. I feel as if my body is melting. とても変。体が溶けて行く感じ。
I can no longer see myself. My shape is fading. 私が解らなくなる。私の形が消えていく。
I feel the presence of someone who is not me. 私でない人を感じる。
Is someone there, beyond this? 誰かいるのこの先に。
After recognising that her self is not merely "this object is me," her form melts away, revealing something that at first appears to not be part of herself, "I feel the presence of someone who is not me," as it is not the result of the bonds between her and other people. This is her soul, or Rei's true self as Lilith.
The line "very strange. I feel as if my body is melting," is reminiscent of one of Shinji's lines in episode 25:
“ Shinji: What is this sensation? I feel like I've experienced it before, as if the shape of my body is melting away. „
