Reality Shift

Reality Shift (リアリティシフト) is a gameplay element that appears in Kingdom Hearts 3D: Dream Drop Distance. When an enemy or a certain object in the field is marked by a pink, oval-shaped reticule, the player can press and  simultaneously or swipe downwards on the touchscreen to activate the Reality Shift, which requires players to complete an action on the Nintendo 3DS's touchscreen. Reality Shifts can be used to damage nearby enemies or to interact with the field, often allowing access to new areas. When the Reality Shift is activated, Sora or Riku dives into the bottom screen, and the action on the top screen is paused until the action is completed; furthermore, the character does not take damage until the Reality Shift is completed.

Each playable world in Dream Drop Distance has at least one Reality Shift associated with it.
