Spirit Gate to the Dreamland 

I always loved the japanese culture and Shinto-Religion. Especially the Shinto-Gates "Toji" are a motive, I paint frequently.

Maybe, as a symbol, the gate stands for a boarder to cross, for a passage you finish and a new you begin, or even for different states of mind - 

like crossing from the "Day-World" to the "Night & Dream-World"
