I'm a bit skilled in psychological subjects but sadly nearly zero if it comes to dream interpretation.
I don't want to interpret it but I try to share a bit of the knowledge that I have with you.
First we dream very much and a lot without recognizing or remembering often there meaning (if you can really figuring it out) is not very significant and often related with the experience of your last day(s) and here comes comes the big but
if a dream or situation/feelings (in your dreams) repeat there is (how more often the bigger) the chance that there could be a greater meaning behind it.
I can you tell this from myself I had the same half nightmare a few times with breaks between the repeatings. It was not really a logical dream so I couldn't think about a meaning behind it but when I started to look this dream up there was really an explanation which was pretty accurate to my situation.
It's really interesting that there are dreams which a lot of people share for example that you dream about loosing your teeth. Falling down is also very very common.
Your dream is a bit harder to describe as the one I had but maybe try to find something over google or look for website which cover those topics maybe you can find something there.
Often there are different way to interpret a dream and your life situation (work, stress, relationship, problems, fear about future just to name some important ones) play a very important role in finding out an accurate one
There is a last thing that I want to tell you dreams - especially repeating dreams - have a lot to do with your subconsciousness and your subconsciousness knows what they mean. It's not very uncommon that if you think about the meaning of a dream that the first answer that comes to your mind is the right or better said an accurate interpretation but often it's something that we want to deny it.
So that is my tip for you: calm yourself down and then try to think about your dream at the beginning try to find only spontaneous ideas maybe write them down.
Repeat that a few times maybe at different times maybe you find a little clue and then maybe after 3-4 times doing it thing deeper and BE HONEST to yourself. Also question your thought especially the one you are about to deny.
I hope I could help you a little bit with that
