I believe your mom in this dream may have a double meaning. It is your mom but she is also representing the Holy Spirit as well. The bible tells us that we need to forgive before we can receive from the Lord.
Read Matthew 5:23-24
She is giving out food, could be provisions spiritual as well as spiritual food which is the word of the Lord. It appears you have something against her. I believe the Holy Spirit is asking you to forgive your mom. He has blessings for you but until you release her, you will not be able to partake in the blessings that Holy Spirit is giving in this season.
pray about this
