In the interpretation of dreams in Islam, yo chew food other than for grinding or eating one's meal means an illness or loss of appetite. Chewing gum in a dream means earningmoney coupled with ugly words that will grow to become a big fight and that will lead to a court appearance. The source of it all begins with greed.
Anything that is chewed in a dream means an exchange of words. The only exception to it is chewing a stick of sugar cane in a dream. In that case, it means lauding someone or hearing pleasing words one desires to hear over and over.
If one sees himself exaggeratedly chewing his food in a dream, it means disdain and indifference about seeking an honest livelihood. Swallowing food one should chew in a dream means debts, or collectors standing at one's door demanding their money.
