Blue humming and vibrating sphere in my room

I was awakened by a humming noise coming from the floor in the corner of my bedroom. I couldn't move.  I tried to call my father, but could only make a noise through locked jaws.  Maybe 5 to 10 seconds went by before I could force a loud enough noise to emit from my mouth that was loud enough for my father to come running down the hall and into my room to see what was going on.  I told him the was a blue ball of something that was humming and vibrating and undulating in the corner, but was gone when he busted into my room.  He said I was having a nightmare, but I hadn't gone to sleep yet.  I sure on this point.  After my father went back to his room I tried to go to sleep.  After I laid there for maybe a minute after he left.  I started feeling like someone was present.  There in the corner of my bedroom came the humming and vibrations again.  I was so scared, but forced myself  to look at it.  It was a blue sphere of light that was completely obscure and looked like it was throbing and vibrating and humming.  I yelled good and loud for my father again.  He came running back into my room only to see nothing when he turned the light on.  That's it.  That's all that happened, but it did indeed happen.  I'll take a polygraph or truth serium or whatever anyone wants me to take, but I was not asleep and this did in fact happen to me. It was around 1962 or 63 and I've never mentioned it as I didn't want anyone to think I am nuts or was exagerating.  I DID HAVE THIS HAPPEN AND I SWEAR ON MY MOTHER'S GRAVE AND I DON'T CARE WHAT ANYONE SAYS.......... I SAW IT AND HEARD IT AND IT DID INDEED HAPPEN.
