Dream Events are extreme events in Mario & Sonic at the Olympic Games. They contain fictional or abstract features (items, special abilities, etc.) and must be unlocked.
Dream Events also make a reappearance in the sequel, Mario & Sonic at the Olympic Winter Games. They, as the ones before, contain fictional and abstract features as the ones before. They also need to be unlocked in order to play them. Unlike the Dream Events from the past game, these Dream Events take place in Mario and Sonic locations.
Dream Events re-appear in the Wii version Mario & Sonic at the London 2012 Olympic Games, which, unlike the previous games, are already unlocked. Dream Events do not appear in the 3DS version of the game.
In the 3DS version of Mario & Sonic at the Rio 2016 Olympic Games, Dream Events are known as Plus Events. Unlike previous games, they do not take place in locations from the Mario and Sonic series. Instead, elements from those series are placed in the event instead (ex., In 100m Freestyle Swimming Plus, a Thwomp creates waves that need to be avoided on the first length and can be ridden on in the second length). Each Plus Event isn't named "Plus 100m," instead it is named "100m Plus."
