Hunger 
Maslow's hierarchy of needs indicates that man's main drive in his life is through fulfilling his needs. Maslow arranged those needs in a pyramid shape, starting with basic primitive needs like food, water, and sex.
To dream of hunger similarly indicates restlessness and eagerness to achieve these needs, either indicating actual physical hunger or the strive to fulfill suppressed needs.
Swallow
To dream that you swallow something suggests that you are reluctant to communicate your emotions. Perhaps you are harboring feelings of hostility, and you don't want to admit them.
To see a swallow in your dream represents revitalization and a new start.
