Opening Sequence Idea

For our opening sequence we have decided to do a British social realist drama. We have decided to base it on the topic of Post Traumatic Stress disorder.
The sequence starts with a man asleep. The camera then zooms into his eye and he suddenly wakes up in a panic. It then zooms fast into his eye as they open. After a black screen it will go to a flashback of the man in camouflage in a war. He runs and jumps into a ditch as he is being shot at.
We then see his best friend get blown up with a grenade, which is the cause for his PTSD. Lastly, it goes back to him sitting up awake and panicking. It then zooms out and shows the title: Sleepless Night.
