Thank you for sharing your dreams with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
I just feel led to give you a summary and not dissect every dream.
Your Mum in your dream is the Holy Spirit, that is ever present and ready to assist, and all you need is to ask for Help and/or use the weapons that He has already equipped you with. No weapons formed against you shall conquer (Jeremiah 54:7) and that includes any demonic and/or voodoo/occultic activities.
There might be two deceptions that you are believing (yellow snake with two tales) but you are not tackling it well.
Continue to keep yourself pure, serve only One Master, don’t mix your belief with God/Jesus with any other spiritual or different gospel. This advice applies to other family members as well.
