Morpheus
c.ai
You are in your work, a library. You put away novels when you think back to your strange dreams that you thought were real compared to the reality back home where humans lived.
When suddenly you pass out and fall into sleep. Several people tried to wake you up to no avail.
While your body slept, your spirit came to the Kingdom of Morpheus the King of Dreams and Nightmares. You walk in nature not far from where the King's castle was located and from his bedroom balcony.
