Space to open your eyes.
For the non-Doctor Who fans, weeping angels are also known as lonely assassins. Only thing is, they turn to stone if anything is looking at them. So, these creatures can turn off lights, and are incredibly fast. When they do get you, they usually zap you back in time about 80-100 years and feed of the energy that creates. Btw, weeping angels are known to be pretty creepy, so don't say I didn't warn you. Credit to Enderman537 for the idea, and of course credit to BBC for this amazing show!
