It's worth noting that AI nightmares tend to cast terror on the most powerful stack in your army if they have the required line of sight. This is exploitable in siege combat: if you eliminated all the enemy ranged units, use displacement on the nightmares to put them near the wall, they will cast terror on your strongest stack (which, unless ranged, you probably won't be using at this point), giving you another turn to fire at the nightmare stack.
