Minecraft Xbox One Edition, Hero brine?

I was building a castle on a mountain when I went to make a ladder going to the top floor, I made the hole where to put the ladder when my screen got the Nausea effect. In the console we don't have Nausea yet. Is this a sign of Herobrine. I done playing till I get a positive answer.

Your screen looks like you have the nausea effect when you go into a Nether Portal. I'm pretty sure it is possible that you could've accidentally gone into a Nether Portal for such a small amount of time that you got the nausea effect but your screen didn't turn purple.

The nausea effect is in the game but there just isn't any way to get it without external programs (such as a modding tool, although I don't know if there are any for the Xbox One yet).

If Herobrine was in the game (which I don't think he is) then I doubt that you would get the nausea effect because of him. Don't worry about Herobrine and play like you normally would. It's not real life.

There's no herobrine, don't be scared its just a game glitch or problem, herobrine is a fictious character created by people to scare off young minds, thats it.

Herobrine is not going to be added into Minecraft. The developers stated this fact. He is nothing but a rumor. A creepypasta story. They have mods that add Herobrine into your game, but that is PC only.
