• The film has a circular narrative, what we saw at the beginning of the film is exactly what we see at the end, its like a continuous loop
• The whole film is very dream like, it may have inspired films today such as 'Inception' where you don't know whether the main protagonist is dreaming or not, the whole film is so surreal its hard to differentiate what is reality and what is in the characters mind
• There are many significant objects featured throughout the film; a flower, phone and knife. 
• The music in the film builds up tension throughout, every time something more dramatic starts to happen, the music starts to build up
• I think that the flower symbolizes the womans life and the hooded "grim reaper" character keeps trying to take it away from her and she's fighting to get it back, we see that the hooded character has a reflective mirror face so when the woman looks at it, all she sees is herself, so it's like she's is battling with herself whether to take her own life or not, this links to the end of the film where she does decide to commit suicide
