In my mother’s dream she saw her dead mother (my deceased grandmother) giving 2000 rupees to the mother of a boy whom I like a lot and told her that I fix this marriage proposal now you bring members from your side and she (that guy’s mother) started making list of guest and that boy is preparing salad of (cucumber).
Wa alaykum salaam,
This dream can mean that your grandma is giving you the good news about the marriage, because in the realm of the (dead ones) people can not lie. They live in the house of truth.
And Allah (jj) knows best.
