When the dreamer sees a trunk in his dream, then such dream symbolizes the past, old thoughts, undiscovered paths. Perhaps the dream shows the troubles that have not been solved in the past. If you saw the trunk of the vehicle, then such dream promises you the joyful trip you are going to have. If the dreamer saw the trunk of the tree, then such dream could represents the strong personality he has, but only when the trunk is firm and hard. On the negative note, the dream shows your weaknesses, but only if the trunk of the tree is lean and petty.
