I'm sorry to it's been hard going through everything.
Okay pause. Scarlet is a dysfunctional adult that died 2 months ago, we only know this story from her memories we extracted from her brain. I am a neurologist at Dream Incorporated. We specialize in the extraction and recovery of memories.
What you just witnessed were one of the many minutes of her memories after death. Liam was her get away from life… like an imaginary friend, but we do know that her parents died so she created him to compensate for the pain.
The rose gas from the rose is her death and her meeting Liam is her heaven. Never take life for granted, the little things matter.
