Okay, I think you should take a step back from giving this too much importance. Dreams are just mental garbage, leftover BS that our subconscious vomits back in nearly random order. All the meaning is provided after the fact based on your fractional memory of the images and the bias of your conscious mind. Overanalyzing something which is already of uncertain clarity isn't going to be productive.

What I would concentrate on is looking for the source of your discomfort in your real life. Having a disturbing dream might very well signal that something is going on in your life, but obsessing over the dream is very unlikely to help you resolve your real issues.

Good luck.
