Sheffield City Council, whose logo appears on the poster, has denied responsibility.
Mysterious posters asking people if they would know if they were dreaming have been popping up over Sheffield.
The poster, which bears the crest of Sheffield City Council, asks: “Would you know if you were dreaming right now?”
It goes on to list advice about how to tell whether or not the reader is dreaming.
The council has distanced itself from the posters, which appear to be a street art project.
The poster’s advice reads: “A. Check your watch or a clock.
“B. Look at something else.
“C. Check your watch or clock again.
“If you are inside a dream, your watch will display a completely different time when you look back at it.”
The posters have reportedly been sighted around Sheffield Hallam University, with pictures of them doing the rounds on Twitter and Reddit.
One Reddit user joked: “We have to constantly check we’re not living in a dream world in Sheff, what with it being so damn awesome.”
A spokesman for the council told the PA news agency: “We didn’t produce this, so please don’t lose any sleep over it.
“If you saw this street art you’re not dreaming, but check your watch if you’re unsure.”
SHEFFIELD, England (AP) — Ollie McBurnie struck in the third minute of second-half stoppage time as last-place Sheffield United fought back to draw 2-2 with Chelsea in the Premier League on Sunday.
Chelsea had scored twice in stoppage time on Thursday to beat Manchester United 4-3 at Stamford Bridge. But Mauricio Pochettino's team suffered its latest setback at Bramall Lane after twice squandering winning positions.
Thiago Silva, making his 100th Premier League start, opened the scoring in the 11th minute by turning in Conor Gallagher’s corner with a volley that crept just inside the post.
Jayden Bogle evened the score in the 32nd when firing in from a tight angle after Gustavo Hamer's pass.
Noni Madueke restored Chelsea’s lead in the 66th minute after an assist from Cole Palmer, who then had an effort tipped over the bar by Ivo Grbic.
Anel Ahmedhodzic pulled off a last-ditch tackle to stop Nicolas Jackson from extending Chelsea's lead before McBurnie salvaged a point for Sheffield by firing in from close range.
