Meaning of the phrase "Nightmare dressed like a daydream" ?

[Anonymous]

A guy recently told me this. I don't know know what it means or whether it's a good thing or not. Also, I don't know if he was sarcastic :/

A guy who is dress nicely and looks perfect but in reality is a nightmare or bad news in general.. if he were to actually look how he was on the inside he'd be ugly but he looks great on the outside so it is deceiving

loool. he is quoting Blank Space by Taylor Swift. It means you look great and nice, but you're actually a nightmare (obsessive, rude etc.). Watch the Blank Space video and you will probably get an idea

It's an insult. Basically: You look lovely but you're a nightmare to deal with.

He sounds like a dick.

Its a lyric from a Taylor Swift song. It means your bad or evil but, you look innocent and nice.

a nightmare- a bad thing
a daydream- a good thing

also lyrics from a song. it suggests you're a pretty person but you're hard work and a bitch
