Wow, ZenScanner, I LOVE that Wiki! Contains MANY of my favorite children's books.

My DD has also asked the "What if this is all a dream?" and "What if my dreams are what is real and real life is a dream?" questions. She is intrinsically a big thinker--absolutely. I do think this can be quite terrifying and isolating. I've talked to her about the concept of philosophy. She seemed comforted that she isn't the only one struggling with these questions. In fact, she said she wanted to major in it in college.
