Dream of

I am in a room with another girl whom I don't know. I hear or feel evil coming into the room so I decide to hide under te sheets. She tells me that I should no longer hide and finally face him. He is invisible only I can see him I he allows me to see him. I run to a dresser and start pulling random things to protect myself from him. As he gets closer I can't see him but I feel his presence. I throw the stuff and he jut laughs. I remember salt, apparently I have had this dream before and in my dream I recalled throwing salt at it the last time I had this dream and he sizzled. So I think about salt and when I look at the drawer there was salt. I thro it at him and he lays down on the bed with its mouth open. I por salt and he falls asleep. Once he falls asleep I fall asleep as well and now we are in the same dream it this time I can see him. He is in fact my roommate but only in body and form but I know that it is not my roommate. He start talking and laughing at me telling me that I can only see him if we're both asleep. I tell myself I need to run and get away. He gets angry and blurts out "you will never get rid of me! I know where you're going! I know you're next step! It doesn't matter where you go or hide I will always did you! I will never leave you! You can't get rid of me! " I get scared and I wake up from my dream in my dream then immediately I wake up from my dream.
