UFO sighting outside of window hovering 25 feet away

One night my sister called me into her bedroom, and when I got there she tolde me to look out her window and that there was a UFO outside.  
When I looked out the window, I did notice that there was a "Bell-shaped" craft with multi-colored lights and it was hovering just 25 feet away from the window. This was on the second floor of the house.  
t then proceeded to go up and away from the house.  Since that time, my sister has had numerous, I would call events, that have caused her to say that she has been visited by other UFO's, at different times, which has made me think that there may have been many abductions of my sister by these UFO's. 
I have watched, on TV, other people say that they have been visited and been abducted many times as well, ((deleted)) by these creatures inside theses crafts perhaps for the purpose of making hybrids, and one women did think she saw her (hybrid) daughter inside of one of these crafts
