I saw the movie i’m looking for when I was a kid. I think it was between 1987 and 1995.
It was on TV and it was colorful, and in English:
Two ex soldiers having nightmares and apparently every time one of them falls asleep, he dreams that he is in some sort of war (something like Vietnam) and if he dies or injured there it happens for real (something like Nightmare in Elm st. concept).
I remember one scene in particular: They have a green army style sack with lots of weapon and ammo inside. Once one of them falls asleep, he begin dreaming he’s fighting again, and while he engages the fight, he runs out of ammunition. He’s friend, who stays awake to watch him, searches the sack for clips. Finely he finds one, kisses it with satisfaction and puts it in his friend’s hand.
In the dream, a clip suddenly appears in his friend’s hand.
