Well to me that looks like a cobwebb or dust webb, my grandma rarely cleans her house and she gets the same thing only a lot more. Just take some samples and find out for your self, but I am thinking cobwebb or dust webb.

yea thats what i thought but then i found this on wikipedia,

Contrary to popular belief, cobwebs only form when dust collects on wayward pieces of silk produced by spiders or insects. Popular myth indicates that dust alone is capable of forming a chain, with each piece connecting to the next piece, finally forming intricate lines in corners and across furniture. This belief is erroneous.

there's probably a spider that's taken up residence in your room that only comes out when you're not around. there's dust collecting on its webs because you probably don't dust inside your light fixture particularly often.

I'm not sure why this thread is in the conspiracy section though....
