I did dream of this last night, but in a way that I felt I was remembering something, maybe another dream from when younger. I also feel the need to specify it is not graves of the fireflies, even if it won't sound much like it.

It's a story about two young brothers, trying to flea/reach their parents. Probably was an animation movie, felt to me like it was in India. The boys where poor, not wearing shirts, area being hot, buildings where close together.

At first they were running away from another group of kids/teens, hiding from them. I remember a scene where they spent a night in a very cheap hotel, with the manager agreeing to help them hide for a night. They could watch the sunset, feeling at least safe for a night.

Another memory of the two of them stealing some clothes from a store, but with the owners catching them soon enough and calling the police. Seeing they were really poor, she accepted to let them go without the expensive clothes. The police officer eventually ended up catching the youngest one after they had to split due to a pole fence with bars too close to each other for the oldest one.

There was a part where the youngest also nearly died.

Another part where they tried taking the train, but realised they lost some cash and couldn't anymore (left in the clothes they had to give back from the store).

There was more, but the details are escaping me now. Rings a bell to someone?
