Creatures with the Nightmare Template gain the Night Terrors ability.
Night Terrors requires the victim to first be affected by the templated creature's Dream or Nightmare spell, both of which have the mind-affecting and phantasm descriptors. (Nightmare also has "evil.")
However, Night Terrors provides no descriptors. Is this correct? Does it inherit the descriptors from the related spell used to activate it? Is it actually somehow not mind-affecting or phantasmal? What's the right way to rule on this?
Dreamlands visitors
How do these spells or abilities affect a target already in the Dreamlands? (i.e., is lucidly "dreaming" via an occult ritual or directly traveling to the dimension.) What does the target experience in these cases? Can a Dreamlands creature cast Nightmare on another creature in the Dreamlands? What happens?
