When Lex woke up on his own, completely well rested and refreshed, the first feeling he had was of relief that no problems had occurred. It wasn't as if he was suffering from posttraumatic stress disorder (PTSD) but actually yes, that's exactly what was happening.
He stretched in bed, producing several cracks from his various joints. His body no longer did that naturally, as there was no need, but due to his increased control over his body, he could do it anyway. There was just something so satisfying about it.
He spent a couple more minutes in bed, allowing his brain and body to relax a little. Even if nothing was wrong, the moment he stepped out from the comfort of his bed, he would be inundated with work and would have no time for rest.
But the peace eventually had to end. Besides, it wasn't as if he dreaded all the work he did at the Inn. It was quite enjoyable in fact.
