Scary Dream

Yesterday Lucy woke up from her afternoon nap (she hadn't been sleeping long), with a panicky sounding cry. Well, I can't quite describe it, but we both thought she sounded scared (not hungry or tired or any of her usual cries). We both went to her crib and she had a worried look on her face and was all sweaty! She was very clingy and after drinking a bottle she settled back down to sleep (in my arms, which NEVER happens anymore!). We were both pretty sure she had a nightmare. It seems early for that type of thing, but according to Ron's Internet "research" it is possible, even at this age. I wonder what it was about, or which experiences are jumbling around in her imagination. The world can be a scary place for a baby, I suppose, and some of it is unavoidable (doctors visits, strangers, big noisy street cleaner, whatever...). Anyone else have this happen with an infant? I know 10 months is young. Just curious. It's another "first" for Lucy (as far as we know), to wake up crying like that from a nightmare.
