I was on highway 93 in braintree massachusetts, 8:40ish pm, going nw with my boyfriend driving and i look up at this brilliant glow straight out a mile or 2 and maybe as high as that. its a pretty densely populated area, urban, boston just a few miles north, plenty of planes. but this object was moving slowly and whisping just at the bottom of the cloud line, and i could see the glow and shape throw the clouds, but it would also completely disappear and come back like twice. it was the shape of a vr headset kinda, with two or three bright blue lights shining through the white glowy shape. it had to be really big to be the size it was at the distance i was viewing it. its wasn't a glow on the glass, it wasn't a plane, or helicopter or drone, i'm pretty analytical and it wasn't anything i could identify.
