Dragon's Dream (ドラゴンズ・ドリーム) is a stand featured in Part VI: Stone Ocean.
Personality
Dragon's Dream seems to follow total neutrality and apparently believes that both opponents should go into a battle with equal odds of winning. Dragon's Dream is also known to explain exactly how its powers work, as he finds it unfair that Kenzo tries to keeps the mechanics of its power secret to get an edge.
Abilities
The compass uses Feng Shui principles to point towards the direction of both lucky and unlucky areas. Dragon's Dream is capable of taking advantage of this by staying in lucky areas to avoid attacks, and attacking from another person's unlucky areas to inflict the most damage possible. When going for a killing blow, people are capable of placing their limbs in Dragon's Dream's bubble, causing the limb to detach from the person, jettison at the opponent to deliver the blow, then return to the attacker with no harm done.
Despite these abilities, Dragon's Dream is neutral and has a will of its own, and anyone is capable of taking advantage of where the lucky/unlucky areas are after Dragon's Dream reveals where they are.
