Ever just be having the time of your life- only to realize it was just a dream... I was just enjoying myself I had all my "wants" and stuff. Then I just wake up to be disappointed by reality.... It just sucks
And that reality is Appa licking you, with Toph and kattara bending the surroundings to hell. Yup that sucks
It often happen to me~ The worst thing is when you dream getting something what you want and everything good, then you wake up and realized you already got it before but lost it. So I wake up in regret and dissappoitment.
