Stolen Shield Options

I was wondering if it is possible for you shield to be stolen by another. About a year ago I was watching television and messing around with psi a little. I happened to end up watching a show called This is Your Day, and they were talking about protecting a temple in Israel with a spiritual barrier. I watched and listened for awhile and the Rabbi, I'm guessing, started speaking Hebrew and then put his hand up and in English said "Your Shield." Instantly I saw a gold/white energy flash in front of me and then my vision faded into the television. Before they started speaking Hebrew on the show they were saying "it is time to remove the veil" and I saw a dark face with glowing red eyes. After it was over I saw the same face, but its eyes were glowing gold/white like what i saw when they said "Your Shield" I was wondering what anybodies take on this is. It probably sounds ridiculous but if my shield was taken is there a way to get it back or do I have to build a new one?

I'm not sure if anything practically would steal shields given that its quite unnecessary seeing that most shield constructs are more of large flashing bulleyes that disrupt the flow in an area and makes the user more apparent than anything. Alright to get to the topic, if I wanted to steal a shield, I would rather simply grab the shield, pick it up and toss it aside. At least that's what one of the entities that works for me now does in its practice, an experiment with an unwary practioner showed that this loophole is too easily exploited as the person piled their supposedly most potent protective layers in place, only to have them literally held up and thrown away. Leaving them vulnerable. But then again, shields themselves can be turned against their user... for example one may use the shield of another to constrict them, implode inwards or something similar. An idea is to add sentience to your own defenses so they're smart enough to know what to do in any situation.
