From some custom vampire Courts I just posted. Somewhat rough and ready.
Area Drinker -4
The character leeches upon the vitality of their surroundings as a whole: people, animals, plants, and all. Each day, they roll Conviction to feed - this affects a radius in zones equal to ten times the numberical value of the numerical value of the result on the ladder (and the character must remain within this area for the whole day) - the affected area takes on an Aspect of "Depleted," which can be compelled and invoked to cause illness and decreptitude, and against the healing of physical consequences suffered by inhabitants (inhabitant being defined as someone who last slept in the affected area). The effect is cumulative if multiple characters with this power feed.
Manipulate Dream -2
This power allows the character to incite or alter a target's dreams. In general, this is a contest of Deceit vs the victim's Discipline - success allows the character to lay an Aspect on the dreamscape, which can be tagged or invoked to ease further manipulations, or the use of other powers such as Dream Vampirism. Aspects on dreams can be environmental ("everything grows dark"), emotional ("everything is inexplicably frightening"), or an incorporated element or monster ("beware the jabberwock"). [Mortals can take a Lucid Dreaming stunt for Discipline, which allows them to use this power on their own dreams, which counters the manipulations of others]
Dream Vampirism -1
This is carried out using the same system as Emotion Feeding, using the vampire's Decit vs the victim's Discipline - as the name implies, it can only be used on a target who is currently dreaming - however, any Aspects laid on a dream by the Manipulate Dream power can be tagged or invoked to benefit feeding. Some Dream vampires draw on emotional energy, while some siphon life force more directly - the only mechanical difference is that the former inflicts psychological stress and the latter physical - decide which one this character does (they can't pick and choose).
