When I have fallen asleep?

When the next day had come, I woke up at one point. First, what comes to my mind was that it was a workday. When I looked at Megan, she smiled, and when she looked at me, she said, "oh, why your face is so scary?"

"What?" I said, and when she looked at me, I shook my head, and then I said, "work we are late."

"Public holiday," she said, and when she looked at me, I shook my head and then said, "oh right. I forgot about this."

"Oh, well, that I remembered. Time to use the bathroom. You should go for breakfast. Especially as you slept more than I do," she said. 

"Wait, when I have fallen asleep?" I asked.
