Lost time

It was around 1:00 to 2:00 in the morning.  I was babysitting my two nephews and I also had my baby in a playpen  All were sounded asleep.
I could not sleep that night.  So I was downstair and as I was going to walk up the stairs to go into my upstair bedroom. I saw out the window a bright light going off and on. It was over other homes. 
As it began to get closer this light or beam shining down on the ground. It continue to beam in a downward postion on and off.  As if it was in a searching moded.  I was very frighten by this light so I began to start to go upstair to tell my husband.  Than all the sudden, I felt two soft touch on both side of my waist.  
After that I woke up the next morning.  In a sitting position on my downstair couch.  I had no knowledge how I got there or I never remember going to the couch.  
To this day, I lost time.  I dont have any marks or burn on my body.  But, I know what I saw.  I also know that I cannot account for the rest of the night.  I would never have fell asleep on the couch in that postion.  I would have just went to bed.
If anyone in ohio had a similar experience like this. I would love to hear from you.
I hope your guys dont think am crazy.  But this really happen to me.  I wanted to report it because I never knew that this web site even existed.  Am glad that I have some place to tell my story. 
Thank you
