You and up to three other willing creatures you choose fall into a deep sleep, becoming unconscious. Choose a god, you all will be warped into the plane your god is on, you all appear on the plane as an illusion and can talk to the god, yet you cannot go out of sight of the god. The spell ends after 8 hours or when you or the god dispel it. When the spell ends, you wake up with all the knowledge you learned, and there is a chance of getting a blessing or item.
