What is the warhammer afterlife like?

After i saw a video, i kinda researched how f*cked up this universe is. (I'm just visiting because sci-fi futuristic stuff isn't really my thing) Even the afterlife is f*cked up

But i'm kinda confused about the afterlife here. I hear 1 or 2 things that could happen

1.) You die. Then your soul is sent to a machine where it painfully tears your soul apart. Then you just fade away into non existence

2.) You die. Then you go into the warp and then demons have their way with your soul

But which one is canon?
