Have you ever had a burn cleanse?

In a few weeks I am finally setting sail! well flying actually. New life, new start, new country. I have heard of people having a bonfire to get rid of things that maybe hold them back emotionally to the past. Have any of you done this or similar?

I really am wanting to let go of a lot of things. I need to leave things here and move on. Any experiences appreciated, or thoughts or ideas?
