*In the Underworld*
When Leo had first come back into his body after the exhausting session he was able to fully get out of his mind. He had realized what Morpheus meant when he told about what his special bed could do for the mind and the body. Being locked in his mind should have been something scary for Leo who was someone that relied heavily on his mentee. But it did not scare him for he was the most relaxed he had ever felt since the day he was born. Being asleep here didn't only make his full mind go completely blank but it did so for his body too, it gave him a fresh start just like before he was born.
