In case this clears your confusion, you wake up as Nikki's soul rather than Nikki herself, who has forgotten that she took her life that night. Her soul wanders in her house in thirst. On the terrace she sees other souls but they are evil and want to consume her. When she goes downstairs scared, she hears her mother crying and finds out that she isn't alive anymore.
Hope that made a bit more enjoyable for you! Thank you for playing our game! :)
