You say these things attack you in times of weakness. Hm, well, it's not always a jewhovanite. It typically is, but not always. I wouldn't exactly call these things 'good' spirits though. If they truly "only" meant to convey a message then they are vagrants. As to why they would attack you only when you are down, and trying to meditate, I'm not sure I believe you have a mix of jewhovanites, and dark vagrants. Although, jewhovanites are known to take the form of a loved one to get you to become frusterated, or whatever else. As for your aura turning black, that's a direct enemy attack I base this on what you said. That happens *only* when you are meditating.
It's some kind of BS visualization/projection to fuck with you. I've had the same bullshit happen to me. It's better off being ignored, and continuing about your meditation. It makes it a lot more difficult I know, but you have to bite through it, and continue meditating. I still deal with it daily, as I have an irregular amount of harassment currently. Not so much the blackness in my aura when trying to visualize, but it seems that my visualization is tampered with, and it looks different when I am trying to clean my aura/chakras etc..
I recommend using the ALGIZ rune in your room, and household to banish any negative energy, as this can act just like a banishing ritual. Also for those bastards who attack you and make you weak, just imagine the brightest white gold you can around you to literally blind it when they attack, and then do this immediately after.
I use this technique when attacks are too aggressive to ignore, or fight off in regular means. As for dreams, make sure you clean your aura/chakras when you wake up.
