Do four-year-olds dream precognitive dreams?

This just in from dream teacher Valerie McCarney:

"We were in Virginia and like always, my grandson got into bed with me to tell me his dream. In this one , he was in a forest of mean trees. The trees all had faces and arms and he had lots of sticks and rocks to throw at them. There was one little squirrel and he wanted to save him from the trees. He asked me to draw it and I made a quick sketch. 

   "Later that day we took a ride to a Christmas event at Busch Gardens. Old Country was set up as European countries, all decorated for Christmas.
    "We crossed the bridge into Ireland and there was his tree. He said, 'See this is the tree was that in my dream last night.' Then he ran into it. It is the tree in the photo I took.

     "it is so important to get children started young believing in the power of dreams."
