Do the servants in Amnesia actually look like that or is it Daniel's sanity?

I think they really look like that, when you read about Wilhelm and his men it talks about how they appear to be changing after drinking the wine. And for the servants sulking I just assumed that's all Daniel could see was the outline of them where they appear to be sulking, due to the fact that it was kept dark in the castle.

I might be wrong about this, but I was under the impression that they died of poisoning, and the changing (I assumed) to be metaphorical for pain/etc from the poisoned wine. I think that the servants could or could not be monsters, since sane Daniel mentioned finding them creepy (supporting hallucinations), but Alexander referred to 'making' more servants as well (monsters).

One of Alexander's notes mentions his fear of Wilhelm betraying and that his servants were being killed, and says by feeding them wine it would solve both his problems. Killing them wouldn't have gotten him more servants, but changing them into monsters that he controls would solve both problems.
