Zara Larsson suffers from sleep paralysis.
The 'Lush Life' hitmaker suffers from the condition - which means she struggles to move when she wakes up - and admits it is "scary [and] weird".
She told the BBC: "Oh my God, it's scary! Basically, you wake up and you literally cannot move. Your brain is active, but your body is not yet awake.
"It's weird. It lasts half a minute maybe - but it kind of feels like you're trapped there for half an hour. I get it a lot when I'm stressed out, or when I have a lot of things going on."
Meanwhile, Zara previously admitted she thinks female pop stars can "never win".
She said: "Just those typical 'bad' ones, 'bad girls' doing 'bad things' when an equal number of men are doing the same things. Look at all those rock stars from way back!
"Female pop stars can never win, especially when it comes to being sexy, or not sexy, and whether you are owning this, or being owned. You know, looking at Beyoncé, she is owning her sexuality, especially in Lemonade. But it's also like when she and Jay Z are performing together, why aren't you in a bathing suit, Jay?"
And the blonde beauty insisted Taylor Swift isn't opinionated enough.
She said: "I think it's lame to hate on Taylor. I saw people hating on her for talking about the Women's March and not going. I feel like, yeah, totally, that sucks - you've got to put your money where your mouth is. But it's not really a problem to me.
"Women are being raped, beaten up, killed. LGBTQ people are being killed for loving who they want to love. And Muslims can't get into America because they're Muslims. There are so many problems going on in the world. Is it really worth focusing on Taylor Swift and if she's a real feminist or not?
"I would like her feminism to be a little bit more inclusive - more intersectional. Because she does have a lot of followers and can make a difference. She's being very nice on every subject, because I feel like she doesn't want to step on anyone's toes.
"She could have Trump supporters who are her fans, and maybe she doesn't want to offend them. She's like, 'Yeah, feminism!' but then does it actually say anything, maybe? As long as her intentions are good."
