This happened twice last night, its almost as if I'm not fully in the dream. Here's the one I remember better; I was in the town library talking to my friend, and then I realized that this wasn't the library, it was bigger. So I tried to put my fingers through the wall, but my dream body wouldn't budge, it just kept talking. Instead, in reality I stuck my fingers out, hit the wall and woke myself up. What do i do to exert control over my dream body instead of my real one?
