If a Fear or Event effect causes damage, can Bringer of Dreams and Nightmares still use it?

Fear and Event cards are not Powers, so the special rule To Dream a Thousand Deaths does not apply. Thus the player who is playing Bringer of Dreams and Nightmares can, for instance, do real damage with the Dahan Raid fear card.
Thematically, the Dahan are actually doing a raid in the real world, it is not just a nightmare caused by Bringer. It also doesn't matter if it's a choice Event you pay Energy for: the damage is still real.
Similarly, if Bringer uses a Defense power, the Dahan deal real damage during the Ravage phase as normal; it's the Dahan dealing damage, not Bringer.
