As the Doctor shined at the final occurrence of the final stage of his regeneration, he reached out to his companion's hand. Now former companion Clara Oswin Oswald that is, "don't go" she said as tears ran down her cheeks. Just before he could ever say one last goodbye and not to worry also to feel her touch for one last time, his body slammed backward towards the TARDIS console behind him and everything just seemed to finish.
Then when he thought he'd vanish into oblivion, the Doctor felt a gentle breeze tickle his nose. He felt himself lying upon sand and small rocks. The air smelt of the sea. He heard waves hit the shore somewhere around him and cries of birds that flew in the sky above him. Slowly he opened his eyes. The sky was cloudy; the temperature cold, he sat up and saw that he was on a shore near docks. The Doctor didn't find himself wearing the clothes he wore last in the TARDIS but his old clothes. The ragged tweed jacket with the red suspenders and bowtie.
To the Doctor it felt like he had just awoken from a long slumber of dreams and nightmares. The Doctor now felt alive.
