Can you help us better understand the disruption of the deep subconscious by spirit meddlers in terms of what brainwave state it represents?

This indeed is something deeper than the usual Theta state you see with the trance hypnosis and it is above Delta still. But, of course, the conscious mind does not experience the Delta state either, so it is that in-between where this layer resides. It is the part that is just below the level on first awakening where the dream state may be felt and witnessed, and then the person might slip back into sleep once again and be oblivious. On the way to that sleep state, they may be within that deep layer of the subconscious and ruminating about past lifetimes, and in fact, some dreams may be a replay of past karmic events and this will be dreamed about. So it is a brainwave frequency in between Delta and Theta, in that blending.
