Othersidepsychic, Nightmare of a Death Shroud

I went to bed just like any other night, keeping the attachments at bay by telling them to step outside my bedroom door if they were not of God and his white light. They do. One in particular hangs out right in the hallway, even with all the lights turned on at night. My neighbors must think I am crazy sleeping with all the lights on, but I have to. As you will read.

So sleep came pretty fast. Then came the nightmare. I was in my old house I grew up in, in SC and it was dark in the house, no real lights on, or so it appeared to be and Amy my twin was there, even though I could not see her. I felt her.
Then as I laid down on the bed to sleep at the house, a giant sheet came and attached itself to the doorway, like it was being sucked against the frame, blocking me from exiting. Like a plastic wrap or membrane over the doorway. Another sheet came at me and intent on wrapping itself around me but I deflected it with my cross around my neck. I fought it off. It was being caused by a ghost that I could not see but I could feel. A very dark and powerful entity was trying to kill me. I started chasing it with my cross telling it to leave but I couldnt utter the word. No words would come from my throat, just gutteral sounds. When the sheet blocking the door fell down with the appearance of the cross, I ran out into the hall chasing the ghost and in front of me were two more sheets being pulled toward me by the ghost on the floor. Inching slowly, creeping towards me, I saw them move but I could not see what was pulling them, and it was coming right for me. The anger in me grew to the point it was do or die in my dream and I have died in my dreams repeatedly but not by the hand of a evil entity. Why I asked, why me? I remembered trying to yell, to scream anything to tell it to leave but nothing would come from my lips. They were frozen. Only a few syllables escaped my mouth. It was enough. The anger I felt towards this entity was enough to make it leave. The cross around my neck, I held toward it and it ran. Then I remember screaming for my deceased twin sister. I repeatedly screamed her name. Suddenly, I woke myself up. Terrified, breathing hard and absolutely unsure of what I had just experienced. Amy was gone too. She was gone. The atmosphere in the house had changed from depression and gloom of a dark entity to a feeling of being at peace and it was but a dream.
However, in the dream, the ghost, everything appeared real. It was trying to block me, to keep in and to eventually smother me. I assume it was trying to wrap me in a shroud if it could. Even though I managed to chase it away in the process, I was still crying for Amy.
If anyone has a different meaning to what I experienced, I invite you to share with me how you interpret this dream.
