Dreams could reflect all stimulation of an organism, both spiritually and physically. This was a special state amplified by an organism's Sensing Ability.
Therefore, dreams often reflect reality. For example, if one's stomach was pressed in an uncomfortable way, one would dream of being kicked at the stomach. Even dreaming about finding a toilet to pee or something along the lines was the stimulation of one's body presented in a dream.
There were big dream stimulations, and naturally, there were the small ones.
Garen soon found what was wrong with this dream.
He held his finger in the air.
"How can there be paper scraps flying at such a high altitude?" A white piece of scrap gently dropped on his finger.
He smiled softly, and the paper scrap instantly enlarged into an endless white slate that wrapped him up.
