There's a rumor that when the body experiences mass trauma, the mind puts itself into a dreamlike state where everything is normal from which it cannot wake up, in an attempt to hide from the pain.
While the person is in this dream state, they come to accept it as a reality they cannot wake up from.
Occasionally, something from the outer world manifests itself in the dream to try to make the person wake up.
No matter how much you ignore it, it will persistently tell you to wake up. Wake up. Wake up.
