Holding a Red, Red Rose

Calley has these dreams....
Sometimes they come true....
One day, she dreams that her stepbrother--her best friend--is hit by a car and killed.
A few weeks later, she's forgotten about it--well, until she sees him go out onto the street to show her something on his skateboard. That's when the dream comes rushing back to her.
But it's too late.
The car is zooming around the corner before his name manages to get passed her lips.
And then Leo is gone.
Just like that.

Might be triggering to some, as there are scenes with hallucinations, flashbacks, and cutting. If you are triggered by any of these, please do not read this.
