My mom was helping me sacrifice a white cow/bull by holding its neck. The animal was very calm. I sacrificed it with a kitchen knife.
Mom took me to dad, and both held down a woman who looked like mom. I sacrificed the woman with a sword. She was calm.
An anguished dream pointing to the women of your family carrying the burden of livelihood at great cost to the family despite outward agreement, and with increased intensity, guilt and helplessness. If it is the case, seek help.
