Islamic Interpretation of Dreams (Ibn-i Sirin):

(Losing the sense of taste; Masticate) Chewing gum in a dream means committing loathsome sins or indulging in sodomy, for the people of the Prophet Lot (uwbp) used to chew gum.

If one sees himself chewing gum in a dream it also could signify talking too much, or constantly complaining about something, or engaging in a major dispute, or sustaining an argument, or it could mean losing one’s sense of taste.
