Can't think of this movie title.

I think it is a Jordanian movie but not 100%. There is a group of guys who pick trash for a living and one of them finds a little boy in their trash can late at night. He ends up keeping him and taking care of him becoming super attached to him.

In the end it turns out the boy was all in his imagination (and was him at a younger age) and his friends only went along with it knowing he had some psychological issues.
