Body Consciousness
Luckily I now have a handful of body consciousness signals which help me with this. That helps so much more than I can even say because I have always questioned everything I could, looking for best/highest or most foundational truth. That means questioning me, too. That helps when overturning crappy old paradigm beliefs but it sucks if one has a sincere bead on something significant and keeps pitching it out because it might not be right.

Instead of thinking there must be something wrong with the body for feeling a sensation here or there, wondering what the communication is places focus of attention on self in the now and =







It can lead to great insights. The body consciousness is self, not separate, and it will work this way if allowed to.
Even if the sensation is uncomfortable I know it is there to get my attention. And once it gets my attention and I get the communication, the discomfort, most of the time, is gone.
A body sensation can also be a communication about what somebody else is feeling, or energy that they are expressing or holding. I've felt those all my life and had been told that I couldn't -- uh right tell the body that -- but now days I am even sensing probabilities of people having strong energy in a direction of having that sensation futurely so they can say no they're not feeling that but the next week they were.

When Left to Myself
If there is not a recognizable body signal the easiest way for me to figure out how to know if this stuff is their stuff or my stuff is to remember how I be when left to myself.
Succinctly, I can know that drama is not mine because I know better, and I don't care.
For the "I know better" part: Resistance makes things stick. My natural state of being is nonresistant because I know better, because I know what sort of effect that has on my experience. If I somehow got caught up in something and am just noticing, this can also be a choice in moment to drop the resistance, and if something is really sticky it can take a little while of breathing and coming back to myself in order to allow that momentum to slow down, stop, turn around, and head back into ease.
For the "I don't care" part, it doesn't mean I don't care about people. It means I don't care that they are doing manipulative bullshit or power games or judgment or whatever. It doesn't have anything to do with me. As soft/dispersed though I can still be feeling it as if it is mine. It helps me to remind myself I really don't care. Also some people really enjoy drama, and I really don't. I enjoy the heck out of playful adventures, and I bliss out just feeling a warm spring day. One of my other lifetimes must have plenty of drama for both of us, because I SO have no interest over there. So if I'm feeling it as if it is mine and I catch it, paying attention to what I'm doing, like why am I feeling all emo or like I need to engage someone in dramarama, I can step back and go oh yeah, that's not mine.
In both cases it can be because I am standing near or thinking about someone who is all up into that. Buffering helps if it's local. If it's nonlocal then buffering doesn't appear to help at all -- still working on this one. Best option is to quit thinking about that person or group of people doing the drama. Again it can take a few moments to allow the momentum to shift.
The other nonlocal one that I've noticed is if someone has their attention honed in on me, I can be feeling their circuitry, and this one can be trickier because I often don't know who it is or what it's about. Not only is the feeling or thought pattern not mine, but the thought connecting to the person wasn't even me-directed so I have to feel into it and see what's going on. Sometimes it becomes clear and then it is resolved just like that. In this way I figure the openness has its benefits because I just became aware of something I wanted to know. Sometimes it's foggy and hard to shake, and that one is trickier. Sometimes booting everybody out and placing myself in my safe space in consciousness helps.
That's also when it's really handy to have my own hook, my own thing I'm really interested in that can pull my attention strongly into what I am doing.
And sometimes I still feel the fog and chaos -- and so guaranteed I'm still feeling for the people going through this themselves and I'm still working on tweaks and open for solution input. This is a new thing for me, knowing about being dispersed, and I'm tickled I've been able to become so clear about so much in such a short period of time. Also like everything I'm never holding myself up as the be-all end-all IT of completion. The people who think I'm being cocky have seriously got the wrong end of the stick. We're always expanding. So if you've got this already please drop me a line or post.
