I... fell asleep in my room and found myself wandering in a dream like this one.

[He tries to explain, because it does sound pretty crazy when he really thinks about it.]

Then, when I awoke, I felt as though I were drifting again. During meditation, something happened and I woke once more in a new place entirely, a world I have never seen. I believe the dreams are all part of this world, a way of preparing us for our arrival there.

[That's just assumption on his part, but he's trying.]

Is a mage like a witch? They have many witches in this world too.

[He definitely says that like he doesn't really know with certainty what a witch is, let alone a mage.]
