Islamic Interpretation of Dreams (Ibn-i Sirin):

(Earthquake) In a dream, it means a threat by the ruler.

Ifone sees the earth caving in under him, he will suffer a severe chastisement.

An earthquake usually means a bitter illness or a plague hitting the population of the town or locusts or a severe cold weather, or it could mean a drought.

If an evil person sees the earth caving under him in a dream, it means a punishment for his sins or undertaking a long and a distantjourney from which he may not return home.
