I was too tired this afternoon during theory lesson. It was mr johnny's lesson, but i was too tired until the inside me will suddenly tell me go ahead and sleep and dun wake up. That was so scary.. But during theory lesson, i really sleep until "dio chua", normally when people have this kind of scary feeling is when you dream of falling from a place which is high. I still could hear mr johnny's teaching but only not very clear with what he was teaching cause i'm like 80 percent sleeping, 20 percent awake. That's how i felt..
