I was rewatching Ceylan's first work, I saw it only once few years ago, this 17-min short is the director's dedication to his parents. They are also the protagonists of this dream-like silent work, heavily influenced -if not dominated- by Tarkovsky's work (especially Mirror, and Ivan's Childhood).
It's strange that Ceylan never mentioned Tarko as one of his influences (the musical soundtrack on this short is even like the classical clichés Tarko used).
Cocoon is visually strong, also he gives a lot of attention to "earthy" noises (door squeaking, clock ticking, birds....). These are the first and the second (last) parts of it.
Speaking about Tarko's Mirror, this is a very well crafted scene :note how he refrains from following the kids initially, still looking back... then we know he's expecting the lamp to fall from the table, the lens shifts quickly to a hazy reflection in the mirror, afterwards the camera parallels the movement of the kid walking outside, only to frame the flaming fire by the dropping water. The next B&W scene is a dream that bridges the childhood with adulthood by the the reflection of the young mother as an old lady towards the end.
