bad dreams

I have often wondered what little ones dream about, what constitutes a bad dream for a three year old. Well early this morning Eliza woke screaming in terror for me. I ran in she was so distraught and trying to tell me what was wrong. All I understood was "Julie, Julie, Julie." I showed her that Julia was sleeping next to her and was ok. Julia woke up and Eliza just threw her arms around her neck and said “oh Julie."
Once I got her calmed down a bit she finally said, “Mama the gingerbread man caught Julia.”
