Artificial

Have you ever wondered why people can see demons or ghost, or why we see things that would be classified as unknown? What if our world was merging with another at a pace that's so fast that its scary.

After Elizabeth Cross gets into a terrible car crash that not only takes her life but, takes away he reason to live. As she travels to the afterlife she meets with her two younger sibilings that passed away and, they tell her that she has to go through certain trails to determine her eternal fate. These trials are horrifying , no "human" should ever have to face them. Thats just the beginning soon it all fades away and she wakes up.
She wakes to find things thats she never thought were true, and meets with people that aren't nessisarily our definition of "normal". Their goal is to stop the merging of our two worlds and, the only way to do that is to go into an artificial life like state.
If they don't stop this reaction in time will life ever be the same again?
