Famine in a dream is a bad omen. It signifies that the person will experience famine, poverty and struggle in their future. It is believed that a famine dream can cause the death of an individual. The worst case scenario would be if the person has not eaten anything for days before they had this dream.
A more literal interpretation of the meaning of a famine in a dream is it signifies hardship and extreme hunger. This can symbolize many different things in real life but most often we see it with things like poverty, social inequality or starvation. The dreamer may be concerned with these themes or they may want to change them waking up. Another common theory is that this symbolism may represent worries about the future such as drought, famine or other climate changes.
