Dimensional Scream

The Dimensional Scream (Japanese: じくうのさけび Spacetime Scream) is a special ability and also a key plot device in Pokémon Mystery Dungeon: Explorers of Time and Darkness, and also in Explorers of Sky.
It is unknown how one obtains this ability; however, it appears that it functions for both Pokémon and humans since the hero could use the Dimensional Scream during their time as both a Pokémon and as a human.

Pokémon Mystery Dungeon: Explorers of Time, Darkness, and Sky
Early in the games, after the hero picked up an Apple that an Azurill dropped, they suddenly got dizzy and saw a vision of the future, that the same Azurill would be held by Drowzee against his will. When the hero's team went to rescue him, it turned out the vision was right. The Scream happened again just before entering Waterfall Cave; however, the hero saw a vision of the past, seeing Wiggltuff enter the cave through the waterfall. It was revealed by Dusknoir that the Dimensional Scream ability shows the user visions of the past or future when someone or something is touched.
Later, while stuck in the future, the hero tried to use the Dimensional Scream to get a clue as to what to do next, but nothing happened. Grovyle later explained that this ability only worked in regards to the Time Gears, and came to the conclusion that it must function differently in the past after the hero's partner mentioned that many earlier visions had nothing to do with the Time Gears at all. Additionally, it's established that the user of this ability must be with a trusted partner for it to work. The hero's partner and Grovyle both fit this role during the hero's respective points in time.

Piplup of Team Poképals experienced two Dimensional Screams in Pokémon Mystery Dungeon: Explorers of Time & Darkness, both of them being visions of the future. The first one came at a night before the team's first mission, showing Piplup an image of himself, Chimchar, and Sunflora visiting the Kecleon Shop the following day. The next time was inside the Labyrinth Cave, where Piplup saw an image of a stone bridge collapsing, allowing him to prevent Chimchar from crossing it and falling into the ravine below.
