Use your imagination to further your growth
It seems that the more pretend play a child does, the more able they are to understand others. So, by either imagining a character or acting out a character, the child is learning about how a different personality might experience things. Therefore, a topic I have explored several times in posts to this blog, compassion and empathy, have their roots in imaginary childhood play.
By the way, even a three year old knows the difference between imaginary and real and, if pressed, will say so. Still, there seems to be an innate value on exploring and making use of the imaginary world in early life.
As an adult individual, interested in your own internal workings and personal growth, there are ways that your imagination can help you: You can always ask yourself, "What if... "
Also, if you pay attention and remember your dreams you can work with them using your imagination. For example, you can ask yourself what any object, place, or person in the dream would say, given the chance. Or you can imagine what would have happened next in the dream had it continued from where it left off. All of these answers will be created in your own mind, thus, they are emanating from your own psyche.
You may learn something about yourself that you were not conscious of before, by using these techniques! (Oh, and have some fun.)
