Power/Ability to:	possess alternate selves

"If your Darkhold is anything like ours, I’m afraid she can do far worst than just summon monsters to come after you here.
What do you mean?
There is a spell, contained within those pages. Corrosive to the soul, a desecration of reality itself, dreamwalking. A dreamwalking sorcerer projects their own consciousness from their universe into another, possessing the body of an alternate-self. They may puppeteer this unholy doppelgänger and pursue their enemies from afar, the possession is not a permanent link between realities but in the fleeting time they dreamwalk, they can do irreparable damage to the universe they invade. So it may not be a demon you face, it may be the Scarlet Witch."
