im a bit confused concerning the car memory and the hospital memory (spoiler warning)

[Tatsuya Hiroki]

Okay so she died in a car accident or in the hospital of leucemia? As we see a grave at the end of the street memory which led me to initially think that she died in a car accident. However in the hospital there is a memory of her medical record which states that she died because of that certain sickness mentioned above.

You play as Madison, who gets in a car accident and goes into a coma for a few seconds. The near death experience inspired her to develop the Soul Cloud.

Astrid (different from Madison) develops Leukemia, and makes a backup of herself in the Soul Cloud before dying in the hospital. However, the Soul Cloud's servers crashed, causing the corruption and loss of Astrid's files. This means that Astrid "died twice" (once in real life due to Leukemia, and again in the Soul Cloud).

The car accident and Leukemia were events that happened to two different people.

Car accident = Madison
Leukimia = Astrid
