Hi, the fact that this water felt “real” to you gives me the sense that this is the Holy Spirit revealing Himself to you as the Living Water.
“Anyone who is thirsty may come to me! Anyone who believes in me may come and drink! For the Scriptures declare, ‘Rivers of living water will flow from his heart.’” (When he said “living water,” he was speaking of the Spirit, who would be given to everyone believing in him. But the Spirit had not yet been given, because Jesus had not yet entered into his glory.)“
