"What theory?" I asked, a bit frowning.
Nine smiled. "You've been asleep for 48 hours. But the strange thing is, when you were sleeping, you stopped breathing and your pulse stopped. At the time we were unaware of your condition or the reason as to why you'd suddenly died. As far as we know, you will only die when you are sleeping and it took two whole days before you came back alive."
I frowned at the thought and tried to make sense of it. I was supposedly dead in two days and today, I live? That's impossible though, because there is no way someone can come back from death. Right?
"But... How is that even possible?" I mumbled the last part to myself.
"That's what we wanted to find out. We're still trying to search for the causes of your condition, but we haven't found any concrete answers yet."
