Question about end of Requiem

[Alszix]

Spoilers below.


Here's what I took from the ending of Requiem. Firstly, in the end of Black Plague, as the room is turning black and everything's vanishing all around you, just after Phillip sends out that email, what sounds like a zombie bursts in and you're lying there and it seems that he's dying. Then the game ends.

Requiem picks up RIGHT where that left off, and the whole game seems like some kind of lonely, surreal dream. And then come the memories... of Red, of Eminiss. It's so obvious that none of it is real, but you're still being tormented with memories of Red. Then at the end of Requiem, when you "meet up with" Red in the incinerator room again, he reminds you of how he wanted to die. Seemed as though he's trying to comfort you. Then if you jump into the incinerator with him, you burn, or if you leave you're forced to relive your horrible memories forever. What I took from it, is that the entirety of Requirm was Phillip in a sort of limbo, progressing through a myriad of his memories, by which he was coming to terms with them as he passed into death on the floor of the examination room.

Just my interpretation.
