DREAMS

After having a thrilling dream,I really have a passion to write down my feeling about that.So ,I choose Blogger as a platform to express myself.However,this type of dream is the dream that i like to have the most.
When i was a child,still at kindergarten,the nightmare that had made me awfully impressive was being chased and almost get murdered by a guy.Never ask me who is the guy.It is either I have forgotten about him or can't remember his physical appearance just when I was awaken from that dream.
Why we have forgotten almost all the plots of dream after awakening?Have you ever been think of this question?
