Dream: I dreamt that I was small, short, petite and stuff...?

The size you or anybody in a dream is actually an indication of how much of a spiritually endowed person this one is. Perhaps you wish to be more knowledgeable, more learned especially about spiritual concerns. That you see long hair also confirms that you would want to be more coquettish, more, shall we say of "a good girl". Your spiritual stature is lacking, small, of little consequence. Forget about your curves and shape and hair, you need to decorate your spirit.
