Light Response - My Room

Throughout most of the day me and my roommates tend to keep our blinds closed.  When I do crack the blinds in my room though, it is filled with shadows.  My room is filled with a grid like wall as the shadows of the blinds are cast throughout the room.  My multiple computer screens cast a small glow from my desk while my computer creates a blinking light from under the desk.  The small bathroom in the corner looks much darker and the light from my room seems to invade the space.  The shadows in the room create a weird ambiance in the room when the blinds are cracked that almost makes me feel trapped.  Maybe this is why I never open them.
