Daydreams?

After the accident, all Alice thinks about is Landon. His smile, his simple pranks, his carefree attitude, everything. She doesn't believe that he's gone. So what happens when he starts communicating with her through her imagination, her dreams, anything he can. Is it really him, or is it her imagination messing with her? Either way, she has to know. After several attempts to figure it out, she's almost ready to give up, but there's one thing left. Desperately needing closure, she starts writing letters, taking pictures, making short videos, anything, and putting them in a box by his grave. She watches the box, hoping something will happen, but was it all really her imagination? All of Landon's appearances to her? The love she began to feel? Or was it real?
