Unusually good quality sleep day

As the title mentions I had an unusual deep/long sleep yesterday even though I slept the same time I usually sleep 1 to 7:30 . Even though it was a leg day, I still woke up feeling very recovered, both the body and more importantly my Central nervous system which is usually not the case. I assumed it might be from food as it was the only thing I slightly changed yesterday. Below is what I ate through-out the day, bear with me.

Morning:
4 egg whites and two bread
100 grams of chicken breast & 4 oreos and a espresso

Afternoon:
100 grams of chicken breast and two bread
100 grams of chicken breast

Evening:

100 grams of chicken breast, 70 grams of quinoa , 50 grms of Milk tea, 50 grams of plantain

Night:
1.5 scoops of protein
220grams of Mango
25 grams of Frosties

Does anyone know what it could be? And has anyone else felt like this?
