I was at my garden with my sis and my friend talking about UFO's and that styf, than a strange light apeared on the sky, like a golf ball but too far of us, going in direction to North, mountain of Sintra. Than another one comes from there, they crossed and the second one comed to Soul like nowone was there to stop it.... Everywone went crazy about that, was a new experience but that's not all, we saw it goes in direction to the Horizont than disapeared on the lane, was not an aircraft becose the lights were nos pincling and becose the colision of tha 2 of them...
