Hello I Am searching a movie. Please help :)

Hello Ladies and Gentleman,

I saw a movie 2 years ago. It Was for me the best movie I ever saw. But I dont remember the Name.

The movie:

It was animated, but not in anime style, more in the style of "a Scanner darkly". This movie was also with the voice of keanu reevees (im not 100 percent sure about it).

There Was a guy who sat in a room with a psychologist and they discussed very deep topics about life. It Was so much and so fast that I had a hard time to comprehend it.

I felt like this movie discussed everything that life Was about. Truly a masterpiece for me.

This are the only Details I know.

Please help me to find this movie.

Thanks alot 🙏🙏
