Screaming or howling

A couple of friends and I are in a haunted house.We are on a balcony area when one of my friends is grabbed by something invisible, and thrown into a small closet that is up there. I open the closet and she is bound by shackles and chains. We are told that the only way we can free her is if we go into the house, find a chainsaw, and saw her feet off. I look closely at what are supposed to be her feet and realize they are made of plastic. So I feel better knowing they are "fake" feet. The other girl and I enter the house. Immediately we are terrorized by spirits. I am dragged down a hallway by a woman who has sharp pointed teeth, and my friend is dragged another direction. I am able to break free and I run into a room and find my friend there as well. Apparently she escaped too. The room resembles the master bedroom at my parents' house. That is when we hear this terrible growling screaming noise that consumes the entire room. A window is open and wind blows into the room tossing papers and anything light up into the air. I grab a small rock I find on the ground and throw it at the window. "Leave us the f* alone!" I yell. Nothing happens. In fact that only angers it even more. Now I am being shoved and tossed around like a rag doll by this invisible entity. I start screaming. It was actually very frightening. At this point I realize I am dreaming. I call out to anything to help me get rid of this thing. I attempt to summon an angel to combat the evil ghost in my dream, but my attempt fails. Strangely enough though, everything stops for a moment and is calm. This is my chance. I run into the bathroom connected with the bedroom. There is an attic hatch on the ceiling. I try to envision it being a portal to another more friendly realm. I open it, and all I can see is water, hovering in place. I jump up inside and start swimming. Everything is dark and murky at first but gets lighter toward the top. When I surface, I am relieved to find I am in a much more welcoming dream. The landscape looks like a tropical fantasy island. Lots of green, with pieces of pink and purple foliage and plant life. Some areas are a bit pixelated like a video game would be. I try to stabilize it to make them more clear but that does not remove the pixelation. I decide to let that slide for now. I see a couple of tiny people swimming in the water near the shoreline. They remind me of realistic versions of anime chibi people - kind of like Kingdom Hearts. Kind of like this except with bathing suits. I swim to the shore and when i stand up I see a little black chibi boy with a small sun tattoo in the shape of a heart on his left cheek. Right before I start to introduce myself to him my roommate wakes me up from the hallway with a huge belch. I am thoroughly pissed. I had a dream similar to this with the same creepy invisible ghost who bellows that god-awful unearthly scream in my room at night - a couple nights ago. It was short so I never actually bothered to record it on here. In that dream I could not escape, even though I had become lucid. I was paralyzed and physically incapable of moving out of my bed (or waking up for that matter). Eventually I did...but I have to wonder where this ghost is coming from in my subconscious. The next time it happens I think it would be interesting to confront it to ask what it represents.
