Oh shizz, this is what nightmares are made of!!
The Let It Go singer was spotted with blood stains, gashes and creepyyyy bloodshot eyes, literally!
If that doesn't give you nightmares, we don't know what will!
Our favorite Dem Dem went from ultra sweet and sassy to horrifyingly disturbing!!!!
We wonder if her makeup artist Jill Powell had anything to do with her horrific look last night…
We're glad Halloween is only ONE day a year and not every other month!
Ch-ch-check out some more shots of her spooktacular costume (below)!!
