Dream Researcher

You touch a sleeping creature, forcing it to make a Charisma saving throw. A Willing creature can intentionally fail the saving throw. On a failed roll, you invade the creature's dream. After the first ten minutes, you will receive metaphorical images that point to the target's basic attitude toward the world and the most basic traits of its personality. After each additional five minutes, you will receive a random, equally metaphorical image of a detail of its personality, a topic it is currently preoccupied with, or a detail from its past. While the spell is in effect, you are blind and deaf to your own surroundings. It ends prematurely when the target wakes up or dies. In the latter case, you suffer 3d6 psychic damage.
