Morpheus, Greek god of dreams
In spite of his exhaustion, Ian Mohr had to battle the demon Morpheus, god of sleep and dreams, every night to enter his realm. There were whole nights when the demon was successful in denying Ian entrance, but eventually the man’s sheer fatigue would defeat the sleep god.
As long as Ian entered the dream realm in a state of mental collapse, the realm and the god were safe, but Morpheus could never take the chance that the man might someday gain entrance with some psychic reserves intact.
However even gods err, and after several decades, Morpheus had a minor lapse, one significant enough to allow Ian access with some strength left within him.
This was all that it took, for once in the twilight realm, the guise of Ian Mohr fell away as he recalled his true nature and name: Phantasos, the demon’s brother.
Jealously long ago caused Morpheus to expel his brothers from the neither realms, cursing them with moral identities. Only Phantasos remembered, and only then in fragments of dreams.
Now it was Morpheus who walked the Earth as a man, one who could not quite recall who he was, what he was. Would the human that is Morpheus age and die and then forever cease to threaten to regain the dream world, or would he too remember and retake what was his?
The answer could only be found in a dream, if Phantasos would allow it.
I didn’t get much sleep last night, so this story is a natural consequence.
