Sometimes it seems that we can simply run away from our mistakes, faults or injustices. We can shove them under the bed and let them gather dust while we focus on new plans and challenges. But these shadows of the past don't disappear - they just wait patiently for their time. At night, when you fall asleep, or in moments of silence, they cautiously crawl out from under the bed. In dreams or thoughts, they bring you back to situations that you would like to forget, but have not been able to.
