Well, it depends. If the story and events in the visual novel are very fantastical or unlike anything you've encountered in reality, you could question if it's all just a dream. But often, it's just an immersive fictional world.
The key features include a blend of cosmic horror which often means a sense of dread related to the infinite and unknowable universe. For example, there could be strange celestial events or dimensions. A succubus is a traditional mythological creature known for her allure and danger. In the visual novel, she would be a central character, perhaps using her charm to manipulate the protagonist. The visual aspect is crucial, with detailed backgrounds and character designs that enhance the overall mood of the cosmic horror and the seductive nature of the succubus.
I'm not aware of many specific 'cosmic horror succubus visual novels' off the top of my head. But you could start by looking at indie game platforms. Sometimes smaller developers create unique and niche visual novels with such themes.
Often, in a visual novel, you can determine where you are by paying attention to the background details, the characters' mentions of the location, or any navigational aids given. Sometimes, there might even be hints in the game's title or introduction.
