My opinion is that all our dreams arise from ourselves.
That our dreams are not some kind of predicting the future, and the like.
Our dreams arise from our feelings, the current mood, than that if we are hungry or full, if it's cold or hot...
If it's cold while we sleep, maybe we will dream that we are somwhere on snow, it's the same if we are hungry - we will maybe dream about food.
Do you remember what you dreamed of?
Positive and beautiful dreams can brighten up your day, just as how bad dreams spoil.
During sleep, our feelings and brake rest, therefore what we dream also represents what we really want. Presents the real picture in our head and our wishes in life.
That's why dreams should not be ignored. If you have a problem with something, and dreaming of something related to that problem ... Maybe you dream solution to this problem, do not ignore it, that's probably what you really want!
Also, the brain discards unnecessary information during sleep. In contrast, our brain would overcrowded information that we are not of benefit to block the processes of everyday thinking about the things that we really essential and are necessary.
People who dream of some demanding tasks and any challenges that are before them, are much better at solving them.
The quality and quantity of sleep and dreaming also is determined by the time when it goes to sleep, time of falling asleep to dream, time and number of awakenings during sleep, waking up the morning of the final time as well as the frequency and duration of daily sleep.
Have a good day / night!
