There's two...

This could be a good read, though I wonder how you're gonna cram this into a complete story in only 8 pages (or perhaps you didn't mean that this page is the 1/8:th that you've finished). You appear to have a story, and this little preview raises questions that suggests some backstory and a resolution not too simple.  Sorry, this is really irrelevant. o_O
It's fairly well written, can't figure out what's really going on apart from the fact that they're losing chunks of their minds. But hey, that's a good thing, wanting to know more.
The opening paragraph drags you into some ambiguous knowledge, the story sequence reveals bits of what's going on while not directly stating the situation to the reader. I guess something like this will be the pattern throughout the story, and I'll say stick with it, it makes for intrigue. ^-^

Gahh... sorry for my lame feedback :x

Cheers!
