Ok I have no idea if this is right but let's say you install the mirrors or a machine does or whatever... The mirrors would not start out together so as you put it together the last image there is before it closes (becomes a room of mirrors) would just bounce off all of the mirrors and that is what you would see... Could that happen
If you had a flashlight the light would reflect onto the mirrors but every time the mirror would absorb a bit of energy from the light, causing the mirrors to gradually heat up and the light to slowly die. If you had enough power in your light, you might die of getting overheated. This is just my guess, and I am thirteen so I know nothing.

I know this from a YouTube video by vSause. It was on this subject.
