I believe dreams, to be your spirit getting off your body, as in astral project, but being controled by your subconcious mind. Your subconcious then would then create you a "dream" for that is something you can do at the astral world, and then, would make you live your own fears or problems.
As MistyWench said, it could represent self-enslavement and nostalgia, but, I believe it can mean running from this enslavement, fleeing from it, as you did run from that devil, or at least from that heated iron rod, or, danger. Could mean you can flee from a situation on your life that you think you can't, something that makes you feel "enslaved", but is not much, and you can flee from it, through old friends or friendship.
Maybe also means you need to let go of those old friends, and find new ones, for life DOES goes on, and you can't leave on the past or future. Well, I hope this helped, I am still just a beginner at dream interpretation, but I do hope this opens your eyes a bit!
