You can re-shape the dreams of your target. While this takes quite some time, the effects can be remarkable. Treat this spell as an attempt to Make a Request or Make an Impression, but using your Spellcasting skill instead of the social skill normally employed.

After the sleeper awakens, you may Make a Request or Make an Impression, using the result from having Cast this Spell. You will be aware of the result of this spell, and if it was not good, you can choose to not make the attempt, thus rendering the attempt discarded.
