While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night.

Nocturnal arousal etc. could be explained by creatures causing otherwise guilt-producing behavior. Add to this the common phenomena of nocturnal arousal and nocturnal emission, and all the elements required to believe in an incubus are present. [13] Additionally, some crimes of sexual assault were likely passed off as the actions of incubi.
