『螺旋』

宗教を扱う手前

輪廻・転生に関しては

慎重に在るべきですが

二人に関しては

完全に「ループしている」

印象です

They're seeing mutual many times in the dream.

They're checked with metempsychosis many times in the transmigration, and they're married many times.

Therefore there is recognition in a face each other for this married couple.

Noone can view theses dreams other,so two  can't be believed that they has dreams in the past repeatedly.
