Dream interpretation of hazrat ibn sirin (may allah have mercy on him) said that if one sees that he has eaten sugar, it indicates that he will do something in haste which will cause him regret. and if he sees that someone has put a piece of sugar in his mouth, it indicates that he will be kissed. and if he sees a huge pile of sugar with him, it indicates that he will acquire a lot of wealth. and if he sees that he is selling sugar, it indicates that he will incur a loss, and buying sugar is better than selling it.
