Daydreaming can be a good way to try things and see if you think you would enjoy doing them in person, for real. They can help you to feel better now and when you feel better you are more capable and confident in dealing with stresses in your life. But mostly, I have found that when I just sit and ask myself what it is I want to have in my life I come up blank ... but by encouraging daydreaming I can find things I want to do or have, and at some point soon I think I will finally be able to write down both short term and long term goals. Then I can have something to look at every day to help motivate me to move forward. So I see daydreaming as a good thing, depending on what you choose to do with it.
