Can Creator explain the reason for and experience of nightmares? How do nightmares differ from the experience of souls trapped in limbo?

The nightmare is essentially the processing of stressful and threatening information or circumstances that have befallen the person and there needs to be a way to discharge the negative emotions that accumulate, as well as to do some problem-solving exercises to take action in a way to work through the difficulties that are presented in a sense as a trial balloon. This can heal things to some degree through the discharge of this stress by at least getting it over with even if one experiences harm directly to the person oneself. Most things that are greatly feared, that are non-fatal, diminish somewhat in hindsight because one, after all, has worked through and survived the difficulty. The ability to create a kind of war-game scenario for perceived problems allows a kind of testing ground to work through the challenges. This can be aided as well by the Law of Karma bringing up karmic dilemmas for scrutiny and consideration with respect to seeing their true meaning, the dimensions of the problem they represent, and then the beginning of a process of atonement in some way or another, if only through experiencing the emotional negativity represented by the karmic disorder, and this can begin a process of repayment of a karmic debt, or atonement in a sense through taking on the burden personally if only within the mind and then suffering as a consequence. This will begin a rebalancing of negativity caused to others, for example, or at least give a chance to work through old problems, but perhaps from a newer vantage point with the possibility of finding better solutions and gaining ground and making headway in resolving old karmic dilemmas. There are many ways to heal. The major objective of the Law of Karma is to create lessons for learning so one can avoid mistakes and having to pay a penalty that might be physically uncomfortable or greatly inconvenient through producing a restriction of some kind on the possibilities open to a person, for example, if they develop a chronic debilitating illness as a karmic penalty and then must suffer in some cases indefinitely for the duration of their life. So any way karmic debt can be discharged will provide a benefit, even though unpleasant, so this is yet another function of the nightmare experience—it is both a learning and a rebalancing tool for karma.
