Here's a technique with dreams you can teach JtS to help with-- it is very simple and highly productive.
One idea is that dreams are one of the ways our brains do the re-sorting part of processing heavy stuff-- that following the discharge process (tears, etc.) our minds automatically re-evaluate all the stuff that had been tied up in the un-discharged tensions. And that dreaming is one way we sort of observe that re-sorting process as it occurs.
The idea is that one can be intentional about working with that process-- making the most of it.
So what you do is, the dreamer tells the dream (say it's you), when you recall it the next day. The person helping (say it's JtS) just listens with bright, loving interest.
Once the telling is done, the listener says/asks, "Wow! That's really interesting! Can you tell me about it again?"
The teller tells the dream again, and usually more detail will be described.
The listener can ask non-directive, open-ended questions once it gets rolling, to encourage more detail.
This process is repeated for as long as it seems more detail is coming.
As the recalled details emerge (sights, sounds, etc., feelings, thoughts had while in the dream), what also tends to emerge are spontaneous "Aha!" moments where the teller tosses in stuff like, "Oh! It's like xx {recalled situation}." Or "Oh! THAT's what this is about: xxxxxxx." (Or those "Aha" moments may come later, after the retelling is done.)
When "enough" telling has occurred, the teller will usually spontaneously end with something like a brisk, "OK! Let's move on!"
It doesn't work well in writing-- MUCH more powerful (and fun) to have a live, warm human bean paying attention. Yawning is a powerful sign the teller is releasing the tied-up tension, and should not be interrupted or treated as an embarassment.
One the telling is done, it's a good idea to let the listener have some listening time, for the teller to listen to them for awhile. Maybe not about dreams, but about whatever comes up as the first teller's turn ends.
This kind of listening with bright attention is work, and it usually calls for a little downtime so the energy-drain of listening doesn't accumulate. Taking turns back and forth helps replenish the energy and the detachment of the listener, so that real listening can occur (as opposed to the kind of listening where the listener is actually thinking about their own saved-up business the whole time.
