Hakunin dreams

Hakunin dreams are a series of four cutscenes appearing in Fallout 2, urging the player to find the G.E.C.K.

Arroyo's shaman, Hakunin, appears in the Chosen One's dreams asking them to hurry in saving the village. The dream sequences occur on October 23, 2241, January 21, 2242, April 21, 2242, and finally, on July 20, 2242. If the player locates the GECK in Vault 13, the game immediately plays the fourth and final dream sequence, skipping any previous left dreams.

(or when you have picked up the GECK)
