I can't understand how to use the Scrying pool.Even if I haven't gathered all the necessary materials inside, sometimes I can still view it.Before this, I triggered a dream plot in bed, and I don't know if it's related?
No the dreams are unrelated. The scrying pool allows you to play random events happening in castle (you can also trigger them by talking to the characters). If an event costs nothing, it's because it's currently active in the castle or you already unlocked it.
