Two days ago i dreamt my grandmother (which i never met).
Maybe she wants us to pray for her, which i did.
..and i found a few prayer on the net too
Heavenly Father, in union with the merits of Jesus and Mary, I offer to You for the sake of the poor souls all the satisfactory value of my works during life, as well as all that will be done for me after death. I give You my all through the hands of the Immaculate Virgin Mary that she may set free whatever souls she pleases, according to her heavenly wisdom and mother's love for them. Recieve this offering, O God, and grant me in return an increase of Your grace. Amen.
and this prayer goes to mom too.
