The Promise of Air by Algernon Blackwood

He woke in the morning and decided that his experience of the night had been a vivid dream-experience, although that was not to deny a deep reality to it. A sense of uplifting joy was in his heart that was the rhythm of some larger life. A new lightness pervaded his very flesh and bones; it sent him along the narrow passage to the bathroom dancing, much to the astonishment of the cook who caught a glimpse of the phenomenon as she stirred the porridge; it made him sing while he sponged himself, waking Mrs. Wimble earlier than usual and stirring in her an unwelcome reminder that she was older, stouter than she had been. For the singing brought back to her a fugitive memory of a sunny Algerian garden, where life sang to a measure of blue and gold Romance, now vanished beyond recall. 'Joe's odd this morning,' she thought, turning over to sleep upon her other side.

But Joe, meanwhile, splashed in his bath and went on singing just because he couldn't help himself; his voice was meagre, yet it would come out. He dried himself, standing in a hot sunbeam on the oil-cloth that made him feel he caught the entire sun. Such a deluge of happiness, confidence, natural bliss seemed in him, seemed everywhere about him too. He could not understand it, but he felt it, and therefore it was real. In the rise and fall of some larger rhythm than he had ever known he swung above a world that could no longer cage him in. He saw the bars below him. Alarm, anxiety, worry, even death were but little obstacles that tried to trip him up and make him stumble, stop, and give up existence as too difficult to face. They lay below him now. He saw them from above. He was in the air. It made him laugh and sing to think that such tricks could ever have frightened or discouraged him.
