Afternoon Nap

Thought of having a peaceful sleep just now but I had awaken by some terrifying nightmare. I had no idea what it is but it just keeps bugging me. What I remembered in the nightmare was just some flashy flashy things. It's something like a combination of several scenes flashing from one to another. I remembered it somehow made me trembled. I tried to wake up but it seems couldn't. Something seems to be forcing me to stay inside the nightmare. Luckily, my beloved Sum Yee called me and I woke up at once. I haven't told her about this story yet as I'm afraid that she might get worried about me.
