That evening, Harry went to sleep after transforming into his Animagus form. He was beginning to understand why many Animagi preferred to stay in their animal state; remaining in animal form was indeed much more comfortable than being human.

Being forced to clear one's mind without the burden of messy, chaotic thoughts naturally brought a sense of ease. People suffered because they thought too much. By turning into a wolf, his brain couldn't dwell on so many things, and Harry enjoyed a wonderfully refreshing sleep.
He woke up the next day feeling invigorated. After his workout, he dragged Sirius and Lupin, who were still sleeping in, out of bed.
