What Does Dreaming of a Locust Swarm Mean?
Traditional Interpretation
In the Turkish-Islamic tradition of dream interpretation (Ibn Sirin and al-Nabulsi), a locust swarm mostly points to massed soldiers, a leaderless crowd, or a strife that harms the crops and one's provision; locusts descending from the sky and covering everything can be considered the herald of a trouble closing in on you, of pressure from outside, or of an event threatening your abundance.
Psychological View
From a modern psychological perspective, a locust swarm may represent anxieties multiplying beyond control, outside demands that overwhelm you, or accumulated responsibilities consuming your effort; your dream can indicate that you feel defenseless against matters that seem small one by one, yet crush you when they come together.
By Context
The Swarm Devouring the Crops / the Field
According to traditional interpretation, can indicate that your labor, wealth, or abundance may be diminished by a group of people or by expenses arriving one after another; it may point to the need to watch over a gain that ought to be protected.
For a Single Person
Can indicate that the crowded, scattered relationships around you, and the many people getting involved, may cloud your judgment; that you need calm before setting a clear direction.
For a Married Person
Can indicate that outside interference in your family and household order, unexpected expenses, or many small problems arriving together may prove tiring; setting boundaries may do you good.
Locusts Raining from the Sky, According to Ibn Sirin
In the Ibn Sirin tradition, a rain of locusts descending from the sky is interpreted as a great army coming upon a land, a sudden crowd, or a trial sent by fate; it may indicate that a collective change is drawing near.
