Detect or Enter, and Weave Dreams

Detect or Enter, and Weave Dreams is a spell that the wondrous staff, Staff of Dreams, possesses. 

Of an unwilling creature, the spellcaster can detect the overall tone of the dream. They can not see what is in the dream, but they can tell whether the dream is negative, and how it's affecting the person they are casting it on. After they detect the dream, they are able to change the dream to whatever tone they please. The spellcaster can choose a specific tone by reciting, "I wish this person to have ____ dreams," or they may choose the contents of the dream by reciting "I wish this person to dream of ____."  This person is often replaced with the name of who they are using it on; they can also use this spell on a mass of people. If they do not know the name of the person, simply envisioning their face is enough. 

Of a willing creature, the spellcaster can enter and see the dream. They can also sense how it is affecting the person they are casting it on. After they enter the dream, they can alter the dream however they please. People affected by this spell have reported seeing the spellcaster in their dreams, watching over them as they weave a new tale, a new dream to tell --- spinning the dream in their favor. Others have reported being able to speak with the spellcaster in their dreams.
