Hi Kristen,
That's a pretty powerful suggestion and one that makes sense from a psychological perspective I guess... as Lindamunchkin suggests unfinished business does indeed hold part of us hostage for as long as it remains unresolved. I have particular places from my childhood that I dream about often... mostly from the time when I was just moving from childhood to adolescence- around 12.
I wouldn't be surprised if we return to those places when we are asleep because they were the sites of big emotions, or transition times in our lives. Having said that, I don't think any place or person can steal a part of us unless we allow it.
You might try resolving some of your childhood unhappiness by controlling your dream when you visit that place again. Rather than be sentenced to repeating our unhappiness long after we have left that time, your soul/spirit/ deepest self may be telling you it is time to work it out on your own. You may be able to do this in a light sleep when you can control the direction of your dream best, or you may be able to instruct yourself before you go to sleep that if you visit there, you will say in the dream what you always wished you could say. Dream that those words have the desired effect and result. If you can, recreate the location as sunny and healthy in the next dream visit. Let us know how it works out. Hugs, T
