I've already explained that vampires lose their super-human abilities in the daytime so tend to avoid it, but really there's nothing stopping them from coming out and socializing a little. Same with all the others. Now, having said this, there's also a certain something about the dark that attracts many creatures. Perhaps it is the anonymity the night provides.
Werewolves love the moon. They like to howl at it just like their more animalistic cousins. So they run at night and sleep during the day in the woods or caves. Zombies are also night creatures by tradition. They crawl out of the ground and swarm beneath the stars. Though zombies are actually quite rare having mostly been killed by other Supers afraid that they would give away the existence of Supers to humans on a widespread basis. They can't help being obvious and rather dumb considering they eat each other's brains.
Fairies, nymphs and demons do just as well during the day as at night. In fact they tend to enjoy the feel of the sun. Fairies and nymphs because of vanity and excess. Demons because the heat makes them feel at home. In fact, demons of the deviant variety tend to seek out humans to toy with during the day because it lulls them into a false sense of security. Where do these creatures sleep? Demons DON'T. Plain and simple. They have no need of it. Fairies tend to favor short naps in tree branches when convenient, though down filled beds are also quite comfortable for them. Nymphs will sleep anywhere and potentially with anyone.
Shifters? They are somewhat secretive, but seem to live most like Normals even out of the line of sight. So it would stand to reason they sleep in beds like you and I.
