wtf did I just watch?
It seems you have just watched Angel's Egg (天使のたまご Tenshi no Tamago?), which is a Japanese anime film produced by Tokuma Shoten in 1985. The film was a collaboration between popular artist Yoshitaka Amano and director Mamoru Oshii. It features almost no spoken dialogue, and its spare plot and visual style have led to it being described as an 'animated painting.' Any other questions?
