Was my client’s dream perceiving the existence of new attackers working to drive her children away from her an accurate perception? Is that why the children are acting out?

Indeed, this is the case. As you found previously, her dreams are often prophetic. This is an aspect of her intuitive ability to connect with higher self and receive information she can perceive accurately she needs to know. This has guided her all her life and will continue to do so. So your follow up work with the Protocol was very timely.
