Apart from dreaming of actually being hungry, to experience hunger in a dream suggests that your physical, emotional or mental needs are not being properly satisfied – every human being has needs that require fulfillment.
In real life our stomachs make us feel hungry so that we will add more fuel to our bodies so that we have enough energy to carry out our daily tasks, and so it is in dreams that feelings of hunger suggest we need some kind of input to fulfill some kind of need.
The clues to the needs in your dreams can be in what you’re eating, where you’re eating and who you’re eating with – or what the situation is where you start to feel hungry in your dream.
