This is way off topic of anything I've ever read or seen posted
So maybe I'm crazy, or just paying to much attention to photography related stuff since buying my first dslr, or I was exceptionally tired last night, but...
Last night I was lying awake and looking around the bedroom, which was quite dark of course. I could've sworn that I was seeing noise with everything I looked at just like a high ISO shot. Is this possible, and what causes it?
