I'm kind of torn on this. It was definitely enjoyable but like ...I know it could have been better. 
 The writing itself was really good, definitely has that haunting ethereal style to the dream world that I've come to expect from Seanan/Mira. This should have been a perfect book - sci-fi mixed with horror movies, sign me up! But I was just never able to suspend my disbelief long enough to actually immerse myself in the story. Usually there is so much science in a Mira Grant book that she can talk me into anything but every few pages in this I was questioning everything. And really the answer for 'but WHY would this cause the characters in the scenario to behave in X way' always came back to 'because they are on a lot of drugs that are altering their minds' and that's just ...that's not really good enough for me personally. 
 As a cool sci-fi story or a horror movie spoof it's definitely great, but I just know it could have been better [maybe if it was a full length book] and I kept getting drawn out of the story because to me everyone was just behaving really weirdly. I also don't exactly buy that this dream therapy thing would work in the first place. So I guess I liked the concept, but for once Seanan really failed to sell me on it. Also I kind of hated the ending, but it makes sense that it ended that way so I'm not really holding it against her.
