Imeno no Awai

Description
The Imeno no Awai (夢野間, lit. Field of Dreams) are Mushi that infest dreams. They cannot be truly separated from their hosts, and can cause the host's dreams to become reality. The effect is sometimes falsely assumed to be proof of prophetic ability; however, not all of the host's dreams come true. They live in the pillows of their hosts, and if the pillow housing the Mushi is damaged or destroyed, the person the Mushi associate themselves with is also harmed.

Weakness
Although powerful, they dissolve when exposed to light.

Trivia

 * A similar translation of this Mushi's name is "the space between dreams and reality".
