Maybe this movie is actually about the various states of loneliness: the loneliness when she loves him; the loneliness when she leaves him and grows up alone; the loneliness when she has him briefly and then loses him; she conceives another him, The loneliness that bears everything alone; he doesn't know who she is, loves others, and she witnesses everything but can't speak the loneliness; he recognizes her, relives old dreams and leaves forever, she falls into loneliness again...
The mother-son relationship in the film might be understood as a metaphor for intimacy; the lonely wooden house is like a woman's womb. The symbiotic relationship between mother and child will be broken one day; the lover or the child will one day leave us.
Loneliness at that time may be another ultimate freedom.
