What do you see when you close your eyes.

1) Close your eyes right now for 30 seconds and tell me what you "see".
It was black, but I could "see" the aura of light from my lamp, this faded after a while, and then all I could see then was darkness.

2) Turn off all your lights, and try to make the room as pitch black as possible. If you have to wait till night-time in your wash room or bedroom with the lights killed, that's fine. Keep your eyes open and "see" what you can "see" without the presence of light. If that still doesn't work, try using a blind fold or cover your eyes with a thick cloth.
I guess all I can describe it as is white noise.

3) Follow step 2, but this time close your eyes completely. Again, tell me what you see.
Same as step 2.

Jam it back in, in the dark.
