I have not had much "direct" experience with evil as i feel i have been "protected" for much of my life. Evil spirits are apparently not allowed to do certain things (such as appear directly in front of you as in your vision) or the angels and/or Jesus may intervene. My experience has been likened to "day dreaming" about how creation works and the different levels that are "controlled" via "control stations" (like fancy computers). I see the "battle over creation" between the good and evil spirits at multiple levels, and it becomes confusing at times. I see it as the evil spirits are gaining ground over the good spirits, and now are present at levels in creation that they should not be in (such as in heaven, at some levels). These are the very advanced (in "tech") evil spirits who manage to "hide" their evilness from others through various techniques. Hope this helps. :)
