Hi, 

So I read this story couple of years back at SPN fanfiction.net, but now i cannot find it. It was about the boys staying a hotel, with some really old pictures on the walls. Dean kept saying the pictures were moving ( he was also suffering from insomnia ) . Eventually sam gets captured by this very old camera and gets trapped inside the picture.There was a side case also going on about some train and ean had gotten a cut and that is how he got infected with supernatural insomnia. In the end they burn the whole hotel down to release all the trapped souls.
