You probably keep coming back to that because you want it to be that, most of the strange dreams we have are due to our subconscious picking up on things around us, so anything we hear, watch, smell, etc can effect what we see in our dreams.
Are you sure there wasn't an event that occured before the dream that could have triggered something like this? do you often have vivid dreams like these? Do you often look for magickal meanings in dreams?
It could well simply be that you are looking into the dream for a magickal reason, when in reality it is simply the product of a vivid imagination.
