help me find an anime
I'm looking for an anime series I watched around 2014-2016. It has episodes of about 24 minutes each. The story is about a girl who is dead but doesn't realize it until she arrives at an old house. The animation starts mostly in black and white, but as the story progresses, colors begin to appear in the world. Some scenes use CGI and show colorful tubes or lines surrounding the characters or environment. The girl asks a boy to take her to the old house. The style is unusual and somewhat experimental, not a typical anime.
