Jeff Jarrett Describes Emotional Run-In with Vince McMahon Before WrestleMania 34

Jeff Jarrett says he had an unforgettable "WrestleMania moment" before his induction into the WWE Hall of Fame -- and it had everything to do with his real-life rival, Vince McMahon.

Double J tells TMZ Sports he was preppin' for his big speech when -- for the first time in almost 20 YEARS -- he came face to face with the WWE honcho ... and buried the hatchet on their heated feud.

"For me to connect with him on the stage where I got to do the speech -- it was surreal," Jarrett said.

"It was quick, but a real special conversation ... a real personal conversation we had."

As for the ceremony itself -- Double J tells us why being able to thank US was the biggest honor of all.

Ain't he great?
