Not keen on a Herald that a second herald to be used. Each Herald should be strong enough to stand on it's own.
Haunting Dreams - I don't like penalising players with gate trophies nor on having them make dice rolls every turn. That'll inevtiably either slow the game down or get forgotten. Perhaps a simple 1 Sanity penalty whenever you begin your upkeep are in the Dreamlands , Abyss or Plateau of Leng - this keeps the general intention, but doesn't slow down the game as much.
Perhaps you should start with a Rat Thing on the Witch House that counts as a Spawn and moves on several different symbols. Whenever it is defeated return it to the Herald. It respawns on the Witch House whenever a Doom Token is added to the Ancient One.
Good ideas. I disagree about the stand-alone herald. I think of this one as a gate burst enhancement. Still... I get the general complaint. Other than adding 1-2 doom tokens, it feels like this doesn't do much by itself.

Nice picture by the way. I'm looking forward to someone complaining that Brown Jenkin doesn't look like that ;') I think the picture's better than the non-colored one used by the first Brown Jenkin creator.
