For some reason, I can't get over the fact that the doctor refers to Sanus as "patient Sanus." It's like the epitome of creepiness, and lets the reader know that he's a sinister character much better than any of your descriptions would. I love it!
I don't like this chapter as much, though. It didn't include as much amazing imagery as the other ones did, and thus kinda broke the tone. I mean, the doctor was great-- but I want more! In fact, is there any way that you can continue this story? I want to know what the pill does, and most of all I want more brilliant hallucinations!
Thanks for letting me read this!

You've certainly kept the tone! I like the transformations and the fact that these hallucinations don't speak-- it makes them ever the more effective, and almost reminds me of many of the paintings by Rene Magritte. And that's most certainly a good thing!
This time, I'd like to ask you to show, not tell. You're showing the reader how a lot happens, but we don't really understand Charles yet, mostly because you tell us his emotions instead of letting us figure them out. Tell us that his heart is racing, that he's breathing quickly, that his eyes scan the room for an exit, not that he's "showing panic."
Oh, and by the way, I like that we have a background into Sanus' life with the appearance of the doctor's office. Nice going!

Wow, great imagery! I love the creepiness and surrealism-- it's like a preview for a movie, only consecutive! Truly, a perfect portrayal of a hallucination.
I'd like to mention, though, that the disconnect makes some sentences rather forced. Instead of using so many short sentences, why not use longer, more flowy ones? That would portray madness just as well, and it would be easier to read.
Sorry for being so nitpicky. I really like this one!

WOW, scary, please do write more.
I love your stories. I long for more.
