Although not all type of problems can be solved in dreams, a great deal of them can be.
Dreaming about a particular content in order to come up with a solution is applicable mostly in cases, where you'd benefit from having asolution represented visually (e.
g.
creating a work flow chart for the project you are in charge of, designing something, artistic inspiration etc.
).
It is because while dreaming, we experience a much more intuitive, emotional kind of thinking than in a state of wakefulness (where we mostly use linear, logical type of thinking).
Ideally, you should try to "investigate" your dreamworld in the week following the emergence of that problem.
That's the time when dreams really do try to offer solutions.
How To Solve Problem In Dreams - Dream Incubation The easiest and the most effective way to solve problems in dreams is a lucid dreaming technique called dream incubation:

1. Daydream about your problem (think of what you would like to dream about).
   That way you are planting a seed in your mind, and considerably increasing the chance of dreaming about the desired problem or object.
   
2. Assemble something on your bedside table that represents an image of the problem (a picture of the person you have the conflict with, a blank canvas, a device or project you're working on that's half finished etc.
   ).
   
3. Keep an image if the problem in your mind when you go to bed, and let it be the last thing in your mind before falling asleep.
   
4. After the dream, don't jump out of bed.
   Lie there and try to recall your dream (record anything you remember in great detail, see if you feel any kind of emotion).
   Do not try to analyze the offered solution at this point.
   Only record whatever you are feeling and thinking.
   
5. When interpreting the dream, keep in mind that dreams do not offer you exact answer to your question, but communicate by means of metaphors.
   

Do not feel bad if you can't remember your dream.
After a few attempts you will have a full dream to record.
