Sleep-walking while pregnant..

After a horrible nightmare, and not knowing if I was awake or not.. I woke up standing in my kitchen with a knife. I'm so shaken up. I would sleep-walk as a child, but not often. I haven't since then, until today. Had my first vvfl yesterday. Today, I am now 2 weeks late. Just curious, if anyone else has had issues with intense nightmares and sleep-walking. I really scared myself this morning, and was thanking God, my SOS was at work. Any advice, or similar stuff happening, or has happened to anyone.. would love to hear it. Feeling a bit cray-cray right about now!
