in my unprofesional oppinion it sounds to me like ur under alot of stress.
if im right..maybe you should try to identify it. (the source of the stress)
and just practice reaching lucidity so u can directly deal with it...as to what the dream means exactly i dont think anyone here can tell u that. just try to identify the baser emotions associated w/ the dreams and make ur educated guess from there.
example:if u feel helpless in the dream maybe look at a situation in RL that maybe be making you feel helpless and stressed.
hope i helped
