Bright light, "electrical sensation" and missing time.

Was driving on Hwy 20 in that area, coming from an evening shift of working at Somerset Hospital as an LPN Nurse....planning to join friends  as it was the weekend  and I had the next day off from work. I was driving for about 15 minutes or so, when I was startled by a very bright light, seemingly behind my vehicle at first, than, above me. I tried to turn to my right to see what the light was...could hardly move my head. I started to feel an "electrical" and/or buzzing feeling in my entire body...my hands and arms especially. I could feel this feeling on the steering wheel as well...and I reached out to touch the dash board...all felt "electrical in nature. I suddenly felt the feeling of motion/rising...car and all...heard a voice telling me that all would be alright. The very last thing I remember is thinking, "Oh yes, now I remember, this has happened before"! I found myself in my car/opposite end of hwy  and several minutes/miles down the road, in the wrong direction. No unusual marks or scars. Was not even upset or fearful, for some odd reason. Continued on to my destination. No sound other then a buzzing/humming sound from the light, was evident. No recollection of beings of any kind. Have had other such experiences throughout my lifetime. I am likely terminally ill  and wish to tell of my many experiences. I can type up a report for you  and send it snail mail, with other data/pics/info, if you like. I  feel like these types of experiences should be documented or reported when possible. There is importance to same.
Witness indicates that the date of the sighting is approximate.  PD
