My camera moved up and my character didnt

So i was making a house and i made a waterfall thing outta glass and i went up against the glass and my camera moved up as if i was flying. I changed perspective and i was just standing there, like nothing happened. I tried this on the other sides and i didnt work. If anyone elsse has had this problem before, you know what i mean. I walked away from it and it acted like i had slow falling. Mojang, poease fix!
