I don't think a soul far from home (earth) would be trapped, because it's only "far away" to our bodies, but our souls are spirit, energy, and limitless. I think we would know where to go and where we wanted to be. Spirits who are trapped here usually have had some trauma, and they're mixed up. Remember, time is different for them.
I don't know if I'm right about any of this, just my opinion. btw, good thread!
