The Nightmare of Fabrication Summary:
The Nightmare of Fabrication is a beautifully drawn full-colour manga from Yoshitoshi ABe. The 18 page short story can be found in the Lain Omnipresence in Wired artbook. It's a bonus story which apparently isn't related with neither the anime nor the PS game. It shows characters who were included in the PS game but not in the TV series (like the psychiatrist), but also determinant characters from the anime who didn't appear in the videogame (like Deus).
