Oh, right! I think the dream is doable, so I'll make sure to add it to my notes.
The strange amulet only has those 3 dreams. I was considering a chain of events where you can re-enact the dreams in real life to get something (perhaps a special summon, or another scene), but I think it might be too involved. I really need to avoid getting side-tracked if I want to finish the game. XD
