Imagery 'sticking': You seem to have a means to really ground the imagery, let it take root, in your psyche.
I almost literally place it in there! The way I find it helpful to work is to think of five aspects of myself - heart (feelings), conscious mind, spirit, subconscious mind and body. When I use an image/symbol for psychic protection, I affirm and imagine it in each of these.
When doing this, I have a physical sense of each part of me. Hard to explain, because the other four are still different from "body". But I suppose the best way I can put it is that I perceive each of the five as located in my physical self. For some reason, I perceive my spirit as located down my right side, and my subconscious as between my heart and left shoulder. So the feeling of placing something in them (and also around them) is strong, almost tangible.
Psychic protection: I used imaging angels and light around me, at bedtime, to prevent nightmares. And I used white and gold light, to protect me, from chaos at work. Neither actions were helpful.
I have to imagine things protecting me from within, as well as around me. I perceive some things as approaching from outside, but a lot of things are coming up from inside, so something around me won't be effective for that. I experienced nightmares as wholly arising from within me. Mostly from my subconscious, but I cover everything anyway.
I work with light, not only around me, but also originating within me and shining out of me, driving things like nightmares out and far away.
Do you have any movement/actions with your images? For example, the light moving things away? I always have an image of what it's driving away (with care - something generalised like a black cloud rather than anything specific) and imagine the protection symbol actually moving the thing away from me.
Some other thoughts:
- My images of protection are always safe and positive for me, but I make them fierce in their protection. I did this especially at first. Light for example, I used to intensify it so it would burn to ashes then carry out the ashes of anything bad, evil or frightening. Without doing that, it wasn't strong enough at the beginning.
I don't know how gentle or fierce your angels are, but I would do something like have them be the avenging kind, nine feet tall and brandishing fiery swords - as long as the image is still a safe one for you.
- I have multiple layers of protection. When I first started and was very vulnerable, I used five. (Five different symbols, which I would visualise in turn and in detail for each of the five aspects of myself I work with.)
- As you might gather from the above, I used to spend a long time visualising. About two hours a day at the beginning. It might sound excessive but a) I was desperate, b) I would lose more than two hours of the day trying to deal with the fallout from a nightmare so I'd rather spend the time preventing one and c) it worked.
Now I only have to use two layers of protection (two symbols) and I only spend about two minutes each day unless there's something in particular making me feel vulnerable, when I'll spend longer but nothing like as long as at the beginning.
- My final, failsafe layer of protection is in the form of alert. If all the other things haven't managed to stop something coming up, for example as a nightmare, this final thing immediately wakes me up out of it.
- I've always felt I had to give my subconscious an alternative, gentler way of expressing things, to communicate to it about that, and to listen when it did express things differently. For example, a dream rather than a nightmare. I've had some difficult dreams processing trauma, but none was a nightmare and they were all healing. I have to keep my side of the bargain and pay attention to the dreams. Otherwise I think my subconscious will want to "shout" at me with nightmares again.
Oh this is very long... you shouldn't start me talking about psychic protection. ;) I'm very passionate about it.
