Whew! - So much for the question that I failed to answer!
In a past life regression there are two people involved, the Guide and the Regressee. The Guide generally is left with the task of guiding what seems to be a disembodied intelligence that somehow is centered in the Regressee through a lot of places that are poorly or not at all defined. If done well, this leads to a series of recollections. Ideally, the guidance is totally non-specific, so that whatever is called up comes entirely from the Regressee. Occasionally, I am told, there may be sensible manifestations of whatever is happening, although I never have seen anything interesting.
For the Regressee the hypnotic process leads to a state in which the mind is fully operational, but mostly on hold. This is sensed as a sort of "blah", nothing going on, not much happening inside, no real interest or desire to respond to the outside either. This is a basic meditative mode. From here you can focus on locating spirits in need of rescue, or you can go into your own recollections.
Now the Guide steps in and gives a suggestion to focus on a specific kind of information in a specific manner. This is the "bridge" by which one reaches the spirit world. I use a metaphor of houses along the street of time. Other workers use other metaphors, such as an eagle that carries the Regressee to the spirit world and into the most important lifetime there. Or you might use an escalator idea, that carries the memory into the proper location. Or an elevator, or a space ship or whatever you prefer.
The next thing is that the Regressee's mind begins to put forth imagery. It can be literal, such as all the details of what you had for breakfast, right down to the last grain of salt and the coffee stain on your napkin, or it can be generic, so that you recognize the breakfasting activity, but lose details because they were unimportant. Or it might be a metaphor, so that the recollections are symbolic (this is unusual, but not rare), or very often it surprises everyone by being a recollection of the present lifetime that has failed to be resolved. At times, sadistic childhood molestation pops out here, even though the perpetrators promised that they'd kill and dismember the victim and shove her down the kitchen sink disposal, or something equally wretched.
The Guide asks the Regressee to recall the event, but not to be so involved that it is relived - recollection is enough. "See it as if from a distance, and tell me what is happening," is one way to do this. However, there is no way to negate the existence of an unpleasant experience. So memories and visions appear, some in good order and excellent detail, some in terrible detail and poor resolution. Most of the SSRI type antidepressant drugs inhibit this and cause fragmentation which prevents either a good sequence or clear recollection.
The Guide is responsible for pointing out things to look at. That's because the Regressee doesn't really care. In deep trance there is little interest in anything. So the Guide tries to point out the elements of sequences and attempts to lead the Regressee through a lifetime in a serial manner, more or less as it happened.
Somewhere along the line the Regressee begins to learn how to "think" by using only primary process operations - a sort of emotional thinking process. This may lead to sponteneity.
If the Guide suggests that the Regressee go through a death scene at the end of one or another lifetime, that's the material that occurs. Fortunately, since we have all died thousands of times, it is a safe bet that dying is never really fatal. I've asked about Hell - but nobody could ever find a place that fit the usual "fire escape religion" ideas. Just the souls of people who are so arrogant and rejecting that they are isolated from God and don't care.
After dying, we normally are involved with the spiritual dimension, so it is possible to "go into the spirit world" and to "call for your loved ones" - which generally brings a lot of dead relatives to you to talk and discuss matters that got missed in life. There are similar tricks that work for therapy. You can also ask for a "spirit guide" and hire the most appropriate spirit who wants the job.
And finally, after doing this for one or two hours (most people find that it's too much work to do for longer times) the Guide suggests that you re-energize your body, sending energy throughout, and return to the world "feeling wonderful, alert, aware and fully awake".
Aside from the Guide, it's more or less like going into a deep sleep. To handle that part, I use a video recorder so that you can see what you said and connect with the process.
A side note - you fear hell? There isn't one, unless you have been such a colossal twit that you have to invent one for yourself. Death is said to be easier than being born, which doesn't seem like much reassurance to me. However, there is nothing but love in the spirit world, and if you are willing to be "repaired" in whatever way is needed to become "perfect" you'll have no problems at all. The only thing that really gets changed is attitude.
Oh yes - you can go there and give it a try if you're curious. (See Announcements.) Then, I suggest that you get a copy of Bruce's Home Study Course and start helping others who are in worse shape than you ever were.
That promises you will get VIP treatment.
I hope that helps-
