Does herobrine exist?

So hey people i have just had an encounter with herobrine and it was my first lets play and ill upload it to YouTube as soon as possible so ill tell you the story it all happened a bit like this...
I had just made a herobrine spawner and went into my cave to go mining to find diamond and then I found 2 red stone touches in the corner I got them and carried on down the well lot up corridor
Until I came across a gap in the wall made of cobble stone. I investigated it by braking it and behind it was a little cave a bout 10 blocks long with red stone torches on each side and at the end of the corridor there was a sign saying I know what your planning! I hurried out of my mine without closing the door and went back to my house but the house I was living had disappeared and all that was left was the door and 5 bricks and a couple of torches from the inside but luckily I had another house so I want in there and went to sleep...

This guy didn't see this :( he was traveling.
