You will noT have this problem practicing SFQ!! This article is extremely general. As with anything, there are many kinds of qigong out there, and many levels of masters, and so called masters teaching it. One can, of course, do damage to oneself if you are practicing incorrectly, or , if your master is not qualified to deal with what might come up , within your practice. Again, in SFQ, you do not have to be concerned with this syndrome. If you have questions about your experiences within your practice. Ask. Someone at LS will forward your question to Master Lin, if no one can answer it in through this forum.
Kaiden, your statement about not fully coming back, and being spaced out, or in a sort of hypnotic state, relates to proper closing to one's practice session. Harvesting qi at the end of your exercises puts the qi back in the right places, and wakes you up, brings you back fully in the body, etc.,
after practice.
