Writing practice: the second Last night I had a dream in which I took a bus, near to my home, to a place where seemed to be out of the Earth. It as if took about a month to get there because I saw passengers get off and on a million times. And when I got there, I saw full of people on the street and they were all laughing, but something weird, no sounds there, they laughing in silence. I was scared. Suddenly I saw a stairs and I ran up to it, on the top turning a corner then running down, a floating down actually. I was on that street once again. But this time their laughter was deafening and banshee-like. Then what happening? I woke up, but doubtful if I was still in sleeping because the laughter remained there. I looked around and tracked the sound, my smartphone's alarm ringing, and I remembered, that i set a funny ringtone in it last night, the laughter of a femal ghost, not funny again.

Writing training one Today i saw a chatting topic which is about owning a own home or renting a house,so i try to write a paragrah about it for also training my writing.Wish you to correct my grammar mistake . I myself is renting a flat now,which is small and crowed；expensive,too.Owning my own house is unimaginable for me,for my salary is too low and the cost of a house is too high.If i would have enough money i did not want to buy one too,for it would bind me. Actually,it would run out my lifetime to buy a house.Can owning my own house give me the security,and the peace? Maybe i am not old for wishing of the stablity in my life；i want to pursue more possibilities of my life,wishing to visit more places and learn more kinds of knowledge.House is not a home,which is so big and i was so small,for it would make me confuse that it is my world,it does not make me feel peace,i think.
