"It means a lot to us," Dier was quoted as saying by ESPNFC.
"This is only the third time that England have reached the semifinals, and the first time in 28 years," added the Tottenham Hotspur player.
A 2-0 win over Sweden in the quarterfinals on Saturday helped England secure their place in the semis where they will take on Croatia on Wednesday.
Harry Maguire and Dele Alli were on target for Gareth Southgate's side.
"I want this to be an inspiration for future generations of English footballers. I hope that, when they look at us, they know that everything is possible and that they can also go far," Dier said.
But he stressed that, despite the elimination of a host of big names from the tournament in Russia, England would be taking nothing for granted.
"All the matches here at the World Cup are very hard. Since the beginning of the tournament, we've seen the big teams struggling against other teams that some considered to be weak," he said.
"However, there is no such thing as a weak team in a World Cup. There's a lot of quality here, in every team. We experienced that against Sweden. It was a really tough game. Our great triumph is our unity. We have a really great bond between the 23 players and the staff. We're ready to fight for each other and we have a very strong mentality," he added.
"Everyone has been able to see this since the beginning of the World Cup, and now we expect to be here until the last day."
