LONDON: Taylor Swift may be world’s one of the most popular singing stars, but the American songtress says the thought of performing at empty venues gives her nightmares.

The 26-year-old Bad Blood hitmaker, who has just wrapped her ‘1989’ world tour, says she gets worried that people will not turn up to attend her gig, reported Female First.

“I have nightmares where nobody shows up and nobody wants to see me perform at all. I would just cry. I would just sit on the stage and cry,” Taylor Swift said.

The singer confesses that at times she gets into the self-doubt mode but fans at her concert cheer her up.

“My friends and I talk about this all the time; just being in our 20s, you don’t know what it’s going to be like when you wake up.

“Not every day is perfect. It’s not always sunshine in my brain and sometimes I just wake up with a bad attitude. But I hear people screaming and a switch flips and I’m excited,” she said.
