I don't agree with your interpretation. I would argue that Wanda didn't even know what was real when the whole thing started. Again, one minute she's crying and the next she's married to Vision in a sitcom. That would be super confusing. She had control over certain aspects (like rewinding the beekeeper), but I doubt she thought it was harmful. She remade the town in her image to make it a happy home. And again, this was over a week. It happened very fast, including her giving up her family and happiness.
