Conundrum

Today I had an odd dream which colored the rest of my day. Normally I have great difficulty going to sleep, and I almost never remember any of my dreams. But today I looked at the clock and realized I had but half-an-hour to catch a little sleep before I had to go out. Closing my eyes, I immediately feel asleep.
Please note that the following is a little disjointed, and lacks coherence- it was after all a dream.

********
I was in a house, the architecture just wasn't quite right. The lighting was low; the walls were covered with white wallpaper in some places, in others a pale shade of red. I was seated at a wooden dining table. There were people seated with me, we were having dinner I presume. I felt that I knew these people well, perhaps they were even my family, but yet I'm still unsure. I couldn't see their faces, only their hands. No one talked; there wasn't any sound at all.

*blink*

The next thing I know, I'm on my feet walking through the family room; the lighting here is darker. I make a left and go into the bathroom.

*blink*

I'm come out of the bathroom and close the door behind myself. My left hand reaches out to the left of the green-paneled door I just exited; flipping off the light switch in one swift motion. A few feet away on my right there's now an elderly lady I know lying down on the sofa which previously wasn't there. She has a blanket pulled up all the way to her neck, and she turns towards me slowly.

'I'm sorry, did I wake you?'
'No child, I was already waiting'
'Waiting for what?'

She smiles at me

*blink*

I'm now standing in a long corridor. (This corridor runs from an open area to the right of the family room, I can't gauge its length. But from this corridor, there's another two corridors linked up). I'm facing the door of another corridor when I feel someone pass me; comewhat like a cold updraft. The candles on a table nearby go out and although visibility is unaffected, I see no one. I feel like something has gone wrong; I feel pressured and a sense of urgency. I swiftly move down the corridor towards the family room, more of gliding than actually walking. Now I sense a presence moving off towards the left and I follow it, whilst I still see nothing. I stumble into the family room and I see on the sofa, the elderly woman before (or at least I think it's still her- she's now covered from head to toe in her blanket; which before was white, is now striped black and white)

The dream ends. I've had this dream two times before, yet only now do I remember ever having this dream. I feel like I've been into this house before, yet it seems highly improbable (especially since its architecture is nonsensical).
Okay, so this is probably my paranoia and me watching too many movies, but could this dream possibly foreshadow a death? More specifically the death of this woman? First she says, 'she's waiting', then the next time seen, the blanket is pulled up covering her face? And what's the presence I'm felt but couldn't see? The angel of death? Or is it a metaphor for the cause of death, or the suddenness of it? What's with the color change of the blanket? Why can't I see the faces of the people at the table, yet I remember trivial details..?
