Sheeran is nominated for Song of the Year at the 2013 Grammy Awards for his song 'The A Team', and is also set to perform a duet with Elton John on one of his own songs.
However, Sheeran says that he can't stop worrying about the duet, adding that the thought of it is giving him sleepless nights.
Speaking to US radio station Mix 106.5, Sheeran says, "I went to sleep worrying about the Grammys... Like what happens if I win and what happens if I don't? And what happens if my voice cracks when I'm singing?
"I fell asleep just thinking about it and had this really odd dream. I'm doing the duet with Elton at the Grammys and I had this dream where we decided not to play the song we were going to play and we were going to play this other traditional song."
'The A Team' singer continued, "I forgot to give him the piano reference and he just didn't play. Everyone was really confused and I got told off. I hope it isn't a pre-warning to what is actually going to happen!"

Ed Sheeran recently spoke about his plans to wear a suit at the Grammy awards, after being named GQ's Worst Dressed Man of the Year.
He told The Sun, "I'm going to be wearing a very posh suit to the Grammys. And if I run into GQ I'm just going to stick it to them.
"I've got a proper tailored suit made for me. If I want to be smart, I can be smart, I just really don't care."
