Black Grapes dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Ibn Seerin
Black grapes, although in reality are excellent buit in a dream they do not augur well for the one who sees them.
The reason being that Hadhrat Nooh (AS) cursed his son out of anger. Consequently, the grapes that the son had in his hand turned black. Therefore, in view of this incident, there is no benefit in seeing black grapes.
