I though they just shared the same entaniomorphic relationship.
I think they share an anus.
Aedra (and Daedra) can be seen every day in the concepts they embody. Anytime you think something is beautiful, thats Diabella. Whenever you sell something, thats Zenithar. When you dream thats Vaernima. Azura can be seen every day between 6 and 8 in the morning, etc.
So if you have a beautiful wet dream about a prosttute that you might kill, it's Dibella, Vaermina, Zenithar, Stendarr, Arkay, Akatosh, Mara, Molag Bal, Nocturnal, Sanguine, Namira, Meridia, Dagon, Mephala, Clavicus Vile, Boethia, Hermaeus Mora, and Azura getting together to make that one dream? You've turned godhood into an insane bureaucracy, which gets Sheogorath in on the dream, which brings in Jyggalag, which means Lorkhan, which brings in Sithis shaped anus holes, which sort of means almost everything and everyone contributes to wet dreams in Tamriel. If you don't get why one of those made the list, I can tell why.
