not last night, but the night before

Baby boy has not been sleeping well at night. He sleeps and sleeps and sleeps the day away, but at night he becomes a hungry, hungry hippo who wants to eat all night long. Finally, about 2:00 am a night or so ago, he had finally eaten and fallen asleep. I collapsed onto the bed in exhaustion and was out within seconds. I was quickly dreaming a very vivid dream in which I encountered several people from my past. In my dream, I was catching up with these people and enjoying myself immensely just chatting away. At 3:00 am, baby boy woke up and started to cry. My first thought when I was awakened by his crying was, "Whose baby is that? And why are they just letting it cry like that?" It was then that I realized it was my baby.
