Dream interpretations needed?

I have also has this dream that ended as a night terror. I was following someone and checking out a house when I entered a white room. The person continued down the next dark corridor without me while I stayed in the white room. I was drawn to it. There was something in the corner that called me in and wouldn't let me leave. I saw this dark cloud start forming in the bottom of the corner and slowly rise above me and the room turned cold (I mean I FELT that shit dude!) and it started to float down towards me and engulf me. I saw a dark, hooded figure appearing out of the cloud. It was like a dementor from Harry Potter or a wealth of some sort. I saw its bony hands reaching for me and it came at me really fast and that's when I woke up screaming "Go away, get away, go away" for about 15 seconds or so. I had that dream in a hotel room. My parents heard it too but they just laughed when I told them about it. That dream scares me shitless to this very day, which is why I remember it so well. Any interpretations for this?

I had this one a year or so ago.
