highly repetitive and frustrating dreams

Hello, I am new to this message board.

I have a question however. Lately, I have been having dreams that plague my sleep that are highly annoying and bothersome. Basically, I get stuck in some sort of loop of doing the same thing over and over and over. It is usually doing math, but sometimes it has been solving a Rubik's Cube or walking through a maze. The same basic action repeats over and over, until it frustrates me so much I wake up. The worst part is most the time, when I go back to sleep I will be doing the same thing, unless I do something to make me wide awake before I go back to sleep.

The are not vivid dreams at all, just really blurry. Like I can not envision myself doing math problems, just a hazy world in which I am standing there in a light brownish fog, but for some reason, I still dream that I am doing math. If that makes sense. Anyone know what this is?

I am not really sure what this is but I would say this would make a perfect Dream Sign to get lucid than you can solve the problem.
