Mo and his dreams

Mo loves to tell me about his dreams first thing in the morning.  I think he even adds to them when he's awake.  Yesterday he woke up crying.  I figured he had a nightmare.  So it took me awhile to rock him and try to get him to calm down and tell me about it.  I was not expecting to laugh my a$$ off.  BTW is that possible??  Can someone laugh their a$$ off because I would really like to try it?  Anyway, it was not exactly what he said as the look on his face.  He was sooooo serious when he said he was mad at the sun for making it bright and waking him up before he could finish his dream.  When I started laughing he looks at me so sadly and said "But Mom I only had one more page left!"
