The monster under the bed.
"Don't remove the pillow! The monster will come out!!"
"It's okay! You'll protect me."
"My way of protecting you is to put the pillow there to prevent the monsters from coming out!
You want to release them and want me to protect you! What logic!!"
I drifted back to sleep very sweetly, albeit the uncomfortable sleep position.
