my daughter and i were sitting in the living room reading and watching television early evening when my daughter said ,dad have you noticed the ceiling light is getting dimmer and dimmer.i said i have noticed it for about the last twenty minutes .thinking it may be faulty i turned the light off from the switch on the wall.later my wife daughter and myself retired for the night and said our goodnights to each other.i awoke from my sleep i think about one or two o,clock the next morning and noticed that my wife had gone to the lounge room to get some sleep because of my snoaring.when i was walking down the hallway i noticed the light was on again in the lounge room ,my fist thought was that it had still had some life in it and went to turn it off but remembered i,d turned it off earlier that night, thinking my wife may have turned it on i went to turn it off again but to my surprise it was still in the off position.i walked over to my wife to ask her if she wanted to return back to the bedroom with me but as i went to touch her a small flash of light flashed in front of my face that startled me,not knowing what it was i turn my head slightly to my left when it flashed in front of me again.i thought it might have been lightening so as i went to look outside the house it flashed again in front of me .it was the size of a golf ball and left a shock wave as it flashed.i went out door to see if it could be from an approaching storm but there was not a cloud in sight. i decided to leave my wife where she lay on the lounge and returned to bed ,where i layed thinking what was it was that i had just seen.about one hour had passed when my entire bedroom flashed a light so bright i did not think possible .now i am starting to become concerned as to what is happening in the house.then twenty to thirty minutes later it flashed again but stayed on for about three seconds, it was so bright i could not see any furniture, windows ,wall prints not anything not even the door or ceiling cornice, for a short time i felt frozen but not with fear but with amazement at what i was wittnesing.i lept from my bed and went out to check on my wife and daugher i went to my wife first and told her to get up and wait there for me but she went straight to the bedroom in her awoken slumber i then went to my daughters bedroom and woke her also and took her to my bedroom with me and my wife.the next morning i told my wife what had happened that early morning and she the had remembed that she had also seen flashing lights in our walk in robe and thought it was me turning the lights on and off but then remembed that i was in my daughters room waking her.my daughter noticed us talking and wanted to know what it was that we were dicussing, when i told her she replied that she had seen the same flashing lights but thought i was me or my wife just playing with the lights in the hallway out side her room but it was not us. i have been confused as to what these lights were untill one night sitting in the yard i saw the same flash of light in the night sky it had the same shock wave as it disappead i truely believe that this light had a great deal of intelegence as it was able to manipulate our living room light.i have seen four other ufo,s with wittneses
