Hi, welcome to the board.
I have a theory that dreams are often a manifestation of what's bothering us deep in our subconscious.
So, you could be worrying about something on a deep level, and your dreams could be showing you that, in a roundabout way.
have you tried thinking like that? Asking yourself why you are having these dreams? Chances are, if that is the case, when you start dealing with whatever is bothering you the dreams will stop.
Feel free to PM me if you have any more questions.
