Waltz with Bashir

This film was about a man with repressed memories of the Lebanon war which he took part in. He has a recurring hallucination that he is naked in ad walks out of the water on to the beach. he sees this as  part of one of the massacres. He sees on of his old friends in the hallucination but his friend doe not recall any of this. A lot of people who have been in wars view these memories as trips from drugs they may or may not have done.
