Nightmare:
Dirth ma, harellan
Dirth=tell/speak, ma=me/mine, harellan= trickster/like the dread wolf. So: Tell me, trickster or Speak, my Dread Wolf. something like that
Nightmare continues: Ma banal enasalin. Mar Solas ena mar din
ma=me/mine, banal=nothing [Banalhan is the place of nothing and "an" means place, as we see in Arlathan] enasal = to be grateful for being able to withstand loss, i assume -in is a suffix. Mar = ? but possibly related to ma. Solas could be pride/to stand tall or be referncing his name. ena=to appear or emerge, din=isn't or is not, also used to mean someone who is dead, who no longer is. Possible translations of what all this means are not as simple.
Solas replies, Banal nadas.
Nadas = inevitable. So basically, nothing is inevitable, or something like that
