So it wasn't just a dream!
I use to watch this movie all of the time as a child. Every time my family and I went to Blockbusters, this was the movie I'd get. Several years later, I found myself trying to remember some of the old movies I use to watch. Every one of them, excluding this one, I remembered. From "Little Nemo: Adeventures in Slumberland", I vaguely remembered something about a room where everything was upside-down. I also could recall a flying bed. I would ask my friends if they remembered such a movie, and they just looked at my like I was crazy. This afternoon, we were once again talking about movies from our childhood when I began talking about this one. Finally someone else had heard of it! She remembered the name "Nemo" in the title. So I googled it, and somehow found this!
Now I'm so happy. I shall rent it next weekend!
