Insatiable Hunger of the Swarm

Branch & Claw - 3rd printing
Errata for Major Power "Insatiable Hunger of the Swarm" -- The line starting "Each deal 1 (Fear), ..." should read "Each (Beasts) does 1 (Fear)..."
A corrected version is planned for Errata Pack (Core 4th/5th, B&C 3rd).

When instructed to "Repeat this Power", do you have to obey the range/target land restrictions?
Only if it doesn't tell you where to Repeat it. If a Repeat specifies where to use it, you obey those instructions instead of the usual Range and Target restrictions (p. 19) even if the land would normally be untargetable. In the rare case that the origin land matters when instructed to Repeat a Power in a specific land, it's the same origin land as the original power use.
For example, The Land Thrashes in Furious Pain could be Repeated on an adjacent land without Blight.

If you have a choice between destroying a normal Beasts token and a Beasts token marked by Unearth a Beast of Wrathful Stone, can you pick the marked Beasts? If so, what happens?
Yes, you can pick the marked Beasts, and it's generally advantageous to do so: if it would be destroyed, removed, or replaced, skip those effects.
It won't count as destroyed, removed, or replaced for effects that scale off the number of Beasts that leave the board, like A Dreadful Tide of Scurrying Flesh or Pent-Up Calamity.

Can Bringer of Dreams and Nightmares do real damage (destroying cities, etc) with Power X?
The answer, in general, is 'no'. If the Power says "damage" or "destroy", it doesn't matter if it also says that Dahan, Beasts, Invaders, or anything else are doing that damage, the source is still ultimately Bringer of Dreams and Nightmares and is only nightmare damage.
This applies even if the power has some other spirit doing something (eg, Blazing Renewal). If Bringer of Dreams and Nightmares played the power, it cannot do real damage.
But: note that Bringer of Dreams and Nightmares can "remove" or "replace" Invaders without restriction, can trigger Invader Actions (ie, cause a Ravage, which will involve real damage), can modify how Invader actions work, and can usefully add Defense (without changing how the Dahan deal their retaliation damage in the Ravage).
