Emrys had a dream, a really long dream.
The last thing he remembered was fighting the red creatures and facing his death. However, when he opened his eyes again, he found himself standing on the surface of a transparent sea.
This sea was vast, truly too vast. As far as the eye could see, only the blue sky above his head and the endless sea beneath his feet were visible.
At first, Emrys thought he was dead, but he soon realized that he was still alive. It is just that he had entered a very strange state where he could clearly feel his physical body and sense everything in the outside world, but he could not control his body.
It was weird, too weird!
He was clearly physically standing on the surface of a vast sea, yet he could sense his physical body standing outside, unable to control it. How could something like this be possible?
