to dream or not to dream

I have two children that will go to bed if you tell them to, almost like they enjoy that more than anything.    I wonder what they dream of though when they sleep.  Have you ever thought about it, do they dream about crazy things like purple dinosaurs that eat grey trees.  Or cars that actually talk to them.  I look at my children and I have to wonder what goes on in their heads sometimes.  If they are anything like me they probably have purple ponies or flying kangaroos.  I can see my son having dreams about cars driving people.  Or my daughter dreaming about her prince charming also known as daddy.  I think it's more fun trying to imagine what they are dreaming about just how they wake up or look at you when  you go in their room to get them.  like when they wake up in a bad mood they must have had such a great dream they didn't want to wake up.  Or if they are in a good mood the dream finished and they got the ending they wanted.  Or if they wake up screaming you know something scared them.  You can definitely tell a lot about how a child or even just any person wakes up for that matter.  Then with my seven year old you just hear some interesting things from his dreams.  You know how he depicts his family members for example, a bad guy came in and my husband was the hero and I helped protect the kids in a safe place.  He see's my husband as the protector and me as the loving caring type that he can be safe around.
