I have a question: it seems (considering the Apocrypha main quest) Vaermina is the Daedric prince of "bad dreams and nightmares". if that is the case, I wonder who is the Daedric prince of "good dreams"... Meridia? Azura?

I mean, Vaermina is not -- by far -- a "nice" Daedra and I can't imagine they could be also responsible for good dreams or prophetic dreams. Hence I wonder if there is an opposite equivalent.
