I have no memory of coma, by my research online some people did. For people to come out fluently speaking a foreign language is amazing. We live in language. I too spoke a foreign language when I came out, but have no idea of how or why. I could speak a little of the language before, apparently very well after.
The video below presents the emergence theory of everything. They say that the universe is crystalline, pixelated, importantly consciousness at its core. My only explanation now for speaking the foreign language after coma is that my consciousness must have experienced something in it.
