If you said "Yes" to any one of the three questions above, your dreams are trying to remind you of something that you have been pushing to the back of your mind. There is something within you that needs to come out.
To dream about anything in your childhood means there is something in you that has not grown up even though you have. Physically, you might have grown up and gone about your life in other areas; however, there is an area in your life that didn't grow up.
There is some unfinished business in your childhood that you left back there. It needs to grow up and catch up with you. Until that part of you grows up, you will consistently have dreams where you are right back there in your back yard, on your elementary school playground, or in your high school classroom.
Pay close attention to those dreams that you have about you being a "little you" back home where you grew up.
Get in touch with your inner self, and ask God to reveal to you what He is telling you while you are sleeping. Allow God to show you what part of you needs to grow up so you can be all you were meant to be.
