Somnium is a dream journal for people who dream and have been affected emotionally. This journal can help people reflect on their dreams and decide whether it affects them personally in their life.
The dreamer collects data after experiencing dreams from the previous night. The person records his or her emotions through three different times: morning, midday, and evening. After that, the person describes their dream based on the questions given and illustrates it. Based off from the data, the person then would go to the Dream Index and write down what type of dream they had and what it means. Throughout the day, the person will have to decide whether their dream reflects on their daily mood throughout the day and how it affects them on a personal level.
