I wonder about other thing. I don't remember when (circa 10?), but I remember that some day I fully get a very sad tougth: I can't dream anymore as a child. I have the tendency to run the same kind of "history" in my dreams (obviously, awake!) before sleep then continue it later. I remember that I was playing a kind of war history or something (I forgot), and for the life of me, I can't do it like before. Now I only get stuck, and things are not fluid. Exist some info about this? When is not possible anymore to have (on command) the same vivid dream bending as a child?
