A air craft like sphere in shape , i cant explain what was that, but surely not any plane from earth , it was something like sphere flying in sky it was so clear with some different colors lightining, a ray came from it and reach to the roof of my home and went back , then i realise that long back i kept a huge magnet on my house roof which was much big, but some current was flowing through it due to power leak, so it was generating magnetic rays.
