Have you noticed this on many patients? YES, in many with Suan Zao. Then with Tian wan! Which was shocking. Suan Zao I can understand - too much Zizyphus for the Hun and a lot of pent up anger coming out in sleep if repressed while awake.
If so, are the nightmares really only with the herbs, or did they have nightmares before and they just were not better with these formulas? They said no dreaming at all before, no memory of them. Then BAM! Nightmares. I suspect that dreaming was happening without the herbs and then forgotten. The herbs and acupuncture lifted the 'fog' so to say, as to remember the dreams.
Did they persist as long as they took the formulas? Yes. Stopped formula and no nightmares later, nothing remembered - dreams OR nightmares.
It has happened on Gui Pi too which REALLY surprised me, so nourishing. Since it is happening with all the "sleep" herbs, I see it as a healing crisis of sorts. Patients can be so detached from the different realities of spirit, that when it is shaken up a little, there is a bit of a shock to the system, anything unwanted, undesirable comes up, stuff to deal with, process comes up (in sleep) -especially in these times of great change.
It could also be "too soon" for the herbs - ie treating root vs. branch and v/v.
Was wondering of any others experienced nightmares while using the herbs.
