why do objects appear to be emitting light? It looks like the bed to the right, the pane beneath the window and beneath the couch are emitting light? why? all light sources except a moon outside is turned off.

All of these materials are basic Diffuse BSDFs. the wall with the window in it has a JPEG-texture wrapped on it.

i'm working in Cycles Render btw



Edit: heres the whole shebang with the layout of it all. the sun and the moon are the dots on the very right. the room where the "human" is sleeping on the couch is to the left. everything outside the room is just scenery, so that's why it looks very sloppy.



the "human guy" in pic 1 has nodes like this: 



I have btw tried turning of all the light sources in the Outliner window, does that render light anyway somehow?

uploaded the .blend if anyone is interested
Mystery solved.  You have a lamp object called "sol kon" whose viewport visibility was turned off, but the render was left on.  That's what the light is coming from when you render.
