The Drawing Of Three

1-83 Roland woke up on a beach and on the verge of death and he walks along the beach bleeding out, then he sees a red door in the middle of a rock wall and he walk up to it and right before it he falls down and he passes out and he thinks he is going to die. He wakes up and is sitting along the wall and someone patched him up and took care of him, this woman came and gave him water and something to drink and she told him all these weird stories.

Was it random that he woke up on a beach, and who is the woman that gave him water and is telling him these stories?
