Maybe I'm Crazy

So, the first three nights of Elijah in his own room have gone pretty well, but something happened last night that really unnerved me.

I have his baby monitor on my nightstand so that I can hear him cry when he wakes up to eat. He woke up at 1:00, and I woke up when I heard him cry on the monitor. I went into his room and fed him, then went back to bed and right back to sleep.

At 3:30, I heard him crying in the other room, only more loudly and urgently than before. I looked at the monitor and it wasn't showing that he was crying, so I wondered as I rushed to his room if maybe I had switched the channels by accident and maybe it wasn't picking up his signal. After I burst into his room, I stopped short because he had suddenly stopped crying as soon as I opened his door. I tip-toed to his bed to see that he was completely sound asleep.

I had imagined the whole thing. He was never crying, which was why the monitor 'wasn't working.' When he woke up to  eat at 4:30, it was on the monitor just like usual.

Now I'm wondering if I have lost my mind.
