Hi everyone, i know exactly what you mean, specially when you think people or someone is looking at you weird, but i think this is an energy that comes out from you, then people percive it and may cause them to think what's going on. You know when you repres your energy, somehow need to be realeased, so unscounsciously, not being aware of it, your eyes, your gaze, whatever on you, might "talk" this energy out.
i do have the same aspect, mars conjunct saturn in scorpio, plus in house 5, and i have to say i have allways felt odd when it comes to relationships, to flirt, to have fun, etc, whatever is related to house 5, that is. plus i do have pluto opposite moon. i do respress a lot, a lot a lot, my energies. and its a constant in me to feel look at weirdly.i think people and some women sometimes look at me wrong, and might be only my perception. i dont know. but i star to be paranoic. im starting to have serious problems with it. and i wonder when its just gonna finish.
