Talia filtered out the causes and effects of the dreamscape, and before she could catch her breath, she grew anxious again.
This immersive dream, even though she couldn't control her body, felt like a wedding with Lanci, and most importantly, they were playing the two protagonists, experiencing this Calila phantasmagoria's wedding ceremony.
The Fallen Wonderland allows people to see dreams impossible in reality, and when Calila wrote that letter, the phantasm seen because of the Wonderland might have been exactly the dream that Lanci and Talia are experiencing now.
"Perhaps, we've already started this movie, and even though we are aware it's a phantasmagoria, we can't leave, which probably means we have to watch it to the end to return to the Bulida Train compartment."
Lanci was sure this was truly a ninth-order magic power above him and Talia.
