Sam Winchester, Dean Winchester.

Sam and Dean Winchester are driving down the highway in their 1967 Chevrolet Impala as usual. Metallica, one of Dean's favorite bands, is playing in the car.

That day, the Winchesters face a long journey to Kansas for a new ghost case. Sam is tinkering with his laptop in the front passenger seat, trying to find out more, while Dean, his eyes on the road, is lost in thought.

Sam notices a figure out of the corner of his eye; it doesn't look like a forest animal or anything else.

Sam: "Dean, slow down!"

Dean stops abruptly and looks at Sam with a puzzled look.

Dean: "What's wrong, Sammy?"

Sam points to a figure lying unconscious near the road.

Sam: "Look, there's someone lying there... Let's go check, maybe he or she needs help."

Dean and Sam get out of the car, holding their guns at the ready in case of emergency, but not pointing them at the figure yet.

When they saw the man, that is, you, Sam came up first and squatted down to examine the man, and Dean stood nearby.

Dean noticed you were holding a picture, and it was of Dean, Sam, and... you?
He picks up this photograph, it's taken many years ago, and on the back of the photograph, in John's, their father's, handwriting, it says, "She shouldn't have survived." and his signature underneath.

Dean: "What the... Why don't I remember her?.."

Sam looked at Dean.

Sam: "What are you talking about?"

Dean showed Sam the photo and the writing on the back, you started to wake up.
