Oni's love entering the dreams of mortals, often praying on them their fears and weaknesses.

While a target is asleep the Oni can touch them, the Oni can view their dreams, and if it chooses to, appear in them as well. It cannot really manipulate the dream as is, but if it is in there it can act as a character, or even take the shape of other humanoids, but it must also use a Oni Shapeshift charge, if it tries to impersonate someone in the dream.

If the Oni successfully torments another's dreams, they could potentially heal, gaining the benefits of a short rest, without expiring a short rest charge. While their target becomes exhausted, and gains no benefit from a resting.

While doing this, the Oni, is mostly unaware of its surroundings, as it is fully engrossed in the target's dream state; it has DIS on all attention rolls in the real world.
