I'm fascinated by certain things...like when you turn off the light, the roof seems to get bigger, but when the light is on the room gets smaller...why does it get bigger or smaller?
Cause when you turn the light off, the light is gone making more space in the room. LOGIC101 I'm a genius. Where's my trophy.
Because maybe your light doesn't shine (or at least is darker) on the outer edges of your room so it seems like only the bright parts are your room, but when it's darker you can see the whole thing. I don't really know. I never noticed that.
Spatial awareness. Fallen kinda has the right idea. When there's light in a room you're more aware of the borders that enclose it. In darkness you can't exactly measure the "space".
