Spell Resistance: Yes
You enchant one creature so that anything that happens to its body in its dreams also happens to its body in reality. Any harm, healing, mutations of the body, and even death, which the target creature experiences in its dreams affect its body in reality, manifesting upon their physical body as they are experienced. Changes incurred are permanent and cannot be dispelled. The creature can dream a change to merely part of their body, or they can completely change their entire appearance.
    You may cast this spell upon a creature that is awake or asleep. When the creature sleeps and dreams they will find that in their dream that their dream body mirrors its current physical state.
    Aside from differences noted in the spells description, this spell functions in all other regards as polymorph other (See PHB [#TSR11550] pg. 236). If a change to a PCs form is too drastic then a DM may rule that the character is no longer playable and has become an NPC.
    Material Component: An ounce of fairy dust. Sprinkle it upon the target creature as you cast the spell.
