Interesting. I have an odd problem in that when I drive at night, headlights shining into my rear view mirror instantly makes me sleepy. I don't understand it, and it only started happening a few years ago.
Kenth, you remind me of a mystery that was finally solved years ago.
Out in the boonies of a north eastern state a 2 lane paved road began to experience accidents at night .No reason for this to spring up suddenly, there was a slight curve to the road but other then that just homes and woods on both sides of the road.
All the accidents came to people who were traveling in just one direction. This road was used by the residents with little traffic at night.
Those who were driving and could remember the accident all had the same story, they described a feeling of sleepiness a time standing still feeling and then off the road they went.
After much ado people began to bring in metal detectors even gigerconters---nothing.
The only thing that had changed on that stretch of road in 20 some odd years was a home owner had erected a white picket fence. Why now out of the blue all these accidents.?
Small town, small police force but a darn good one. The police took to driving that stretch every hour, after a few nights a Cop ran into a tree.
In comes the State Police and some unidentified people from the Government.
The mystery was solved and steps taken to remove the danger.
It was a one in 5,000,000 odds that the homeowners who had erected their fence would position it so that the lights of on coming cars would shine and flicker through the fence in a strobe like manner.
We now today know the effects of flickering light on a body, wasn't is just a few years ago that some games for the PC were taken off the market as children were having mini seizures.? Movie theaters were accused of placing subliminal flashes on the screen that the brain picked up on but subconsciously, like You are hungry buy popcorn.
Question, did this begin after you bought a new car or truck.? Perhaps changing the angle of the side mirrors or rear view mirror can help. Do you get sleepy when driving in the rain or at all times. Water distorts our vision and your car lights may be bouncing and reflecting off the road. The auto following you, their lights may be reflecting light from the water that is bouncing all over your side and rear mirrors.
I am not even getting into Hollowgrams or never believe your lying eyes.
