Source: Tafsir al-Ahlam al-Kabir (Ibn Sirin)
Eating in a dream is sustenance and livelihood. Whoever sees himself eating good food in its season will receive blessed sustenance. Sour food is illness and worry. Eating with the right hand is following the Sunnah, and with the left is obeying the enemy.

If the food eaten in the dream is disliked in wakefulness, it indicates something disliked. Whoever sees himself eating with righteous people will receive blessing and goodness. With corrupt people, it is evil and misfortune.

Eating is interpreted as sustenance and benefit, especially if it tastes good. Eating at a feast indicates glad tidings and joy.
