What if SOMA really was all in Simon's dying head?

The "it was all in your head!" theory is a very cliche one. But I never quite get tired to reading them. So it's still an interesting theory to read, and props for fleshing so much of it out! You've obviously put quite a bit of thought into it.

But then I really like theories, even silly or nonsensical ones. :B
