I was watching tv layed in the sofa, when my dog woke up and went to the window really quick, i got up think ing it was going to bark when a cilinder metalic object started to enter through the window(30cm aprox object) making a sound like when you pass your finger from the top part of a glass cup, it stooped in the midle of the room and with a white-transparent beam started to scan up and down the air object,tv and mobile phone then in the same paralel line in wich it came in, it went slowly.I didnt see if it went to the sky or where, i was just still i couldnt move and my dog either through all of this(10-12mins) ,something of that object made us couldnt move despite i wanted.Sorry for my english, its bot very good.
