Bed Invasion and Sleep Laughing

The princess has mastered the art of invading our bed, most nights with out me noticing. Last night however was somewhat different. Both the captain and I were awoken by her laughing heartily. You see she was sleep laughing. After a few minutes the laughing ceased and she was once again sleeping quietly. At breakfast I asked if she recalled having a funny dream, then explained the sleep laughing. She had no recollection of it, never does when she sleep walks.
