Hey there BlueMan,
While your dreams may appear as monotonous and ordinary as they may be, realize that with patience and analysis you can get the best out of them, and work your way up to lucidity. You can try many different things for that matter:
Dream Recall: You should continue journaling your dreams. The more dreams you have, the easier it’s to spot the inconsistencies within the dream itself. I have the same problem you have when I started about a month ago. Being in med school, my dreams mostly include scenery related to school, libraries, books, classrooms, etc. Yet the more time I spend journaling my dreams each night, the best I am able to analyse and search for the clues that give me the idea that I’m dreaming. Ask yourself, are there people in your dream who shouldn’t be there? Are there any people at all? What are you doing while you’re working? What about the tools, are you working with the same tools as always? What are you working on? Is everything in place, where it should be, like in waking life? What are the people saying? Do they even talk at all? Search for the small details.
Both what Dream-explorer and Lucere said are also great ideas you could use. Reality checking whenever you are at work or using autosuggestion might also aid you in achieving lucidity. You could also try and ask yourself, “Where am I?” each and every time you are in a different place or room. Or you could ask yourself “What did I just do?” consistently as well in waking life. Then you can reality check after to prove whether you’re dreaming or not. With time, you can get these specific behaviors to show themselves in your dreams.
Also, the amount of sleep you’re having might also have an impact in your recall and dreams as well. Try getting enough sleep when you can, particularly in weekends so that you’re relaxed enough to achieve lucidity. Stress is also important. It explains why you’re mostly dreaming about work, since it’s the only thing that’s keeping your mind’s attention. I’ve found out that the less I think about school, exams, studying, etc. my dreams tend to be more action packed, extraordinary than before. So, relaxing yourself and clearing your mind is of utmost importance.
I managed to achieve a LD today by using the aforementioned tips for about a month. Who knows, maybe you can get this in a week with consistent trying and effort.
Hope this helps you in your quest.
