This book features a simply drawn boy, maybe even a stick figure. At some point, perhaps in a dream, trees come to life and dance around him. I believe the trees turn to popsicles or lollipops.
Thank you for trying to figure this out with so little information!
Could be The Wish-Tree by John Ciardi: A small boy goes to bed the night before his sixth birthday and has a long, fanciful dream that relates to his wish for a puppy and to the fact that his father has told him he would have to find a wish-tree.
