Minecraft PE changed to Minecraft PC?

Ok here s the deal,

I was building my house and I thought that my sheep should have a play mate. So I decided to try and change survival to creative just for a bit so I can spawn my other sheep. Anyway I did some commands (/gamemode c, /gamemode1, and /gamemode 0) anyway none of them worked so i thought oh well doesn't matter. I got out of mine craft and did some other stuff. I got back in no later than a minute after I exited and the game has changed to PC version. The food bar is there, potions, ect. I have no mods or apps. So how do I get back my original game. What commands do I use?

Minecraft PE stands for Pocket Edition meaning it's the version for phones and tablets. You can't use commands on Minecraft PE, let alone turn it into the PC version.

What gamemode are you in?
/gamemode c (for creative)
/gamemode s (for survival)
/gamemode a (for adventure)

also make sure that you have cheats enabled
