KONY 2012 Founder Jason Russell -- Naked Meltdown is 'Not Who I Am'

KONY 2012 founder Jason Russell is finally speaking out about his naked meltdown ... telling Oprah Winfey, "That person on the street corner ranting and raving and naked is not me."

Russell sat down with Winfrey for the Oct. 7th episode of "Oprah's Next Chapter" -- and tried to explain what happened to him on the day he broke down back in March.

TMZ first posted the video of Russell's meltdown, showing him frantically babbling about the devil and pounding the concrete.

O's people have yet to release a clip of the interview ... but they did release the following excerpt:

OPRAH: "What do you remember, Jason?"

JASON: "I remember me flipping off cars."

OPRAH: "Flipping off cars? Like with your..."

JASON: "With both hands. I remember that just like 'doot,' just like a little memory. I remember running around our lemon tree. I remember ..."

OPRAH: "There were reports that you were breaking into cars?"

JASON: "There are reports. I mean I think I was stopping cars in the street. People said I was laying in the street – it's a busy street – I was laying in the street."

OPRAH: "How did you get your robe off? How do you go from running out with your robe on to your robe off?"

JASON: "Again, it's really hard to explain if people who have never had an out-of-body experience, but it really wasn't me. That wasn't me, that person on the street corner ranting and raving and naked is not me, that's not who I am."

JASON: [I remember] walking around snapping my fingers up and down ... slapping my hands on the ground as hard as I can. Just slapping them on the ground. Talking to myself. Ranting. Raving. Talking about good versus evil, God and the devil. I mean it was just very out of control."
