The 18-year-old is poised to feature in her first Games, and has revealed that winning a gold medal in a World Cup event earlier this year has increased the pressure on her in Sochi.
Cheshire told BBC Sport: "I still feel like I'm kind of in a dream. I suppose winning the World Cup, it has put a lot of pressure on for Sochi to win a medal but to me my goal was to get to the Olympics.
"It definitely feels like a bit of a blur because I'm still young and it doesn't really feel like it. I'm just overcome with excitement."
Cheshire is ranked seventh in the world in the freestyle half-pipe event.
