Seeing an invitation in your dream signifies the beginning of a new journey in your life. If you receive an invitation during the day, it suggests that you want to take a break or free yourself from work-related stress. It may also indicate changes in your life, signaling that it's time to move towards new opportunities.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Invitation" (page 226).
An invitation to lunch or dinner in a dream means taking a long journey. If in the mid-afternoon, it signifies a rest or taking a break from a troubling job. If it is an invitation to dinner in the dream, it means betraying someone under the cover of darkness. If one sees himself planning to invite people to a lunch or to dinner in a dream, it means that he wants to do business with them, or perhaps enter their circles. Consequently, he will be blamed for interfering or entering such a venture. If one sees himself hosting a dinner at
his house, and the guests have finished eating in the dream, it means that he will preside over them. If a sick person sees such an invitation at his house in a dream, it means that he will recover from his illness. Serving food to guests in a dream means the returning home of a dear person from a long journey. If one sees himself sitting at a table covered with all types of food and fruits in a dream, it means that he will be called upon to serve his Lord and to win paradise.
