In 1987, just on the outskirts of Oxford, England, I had a very strange experience. It was about 11.30pm and I was driving along the Oxford ring road, which has nothing but fields to the left. Although it was dark, the sky was clear and I became aware of a bright light about 60 degrees up – almost in front of us and a little to the left. The road is long and slowly turns right, so although it was almost in front of me, it would have been over the fields, some distance away.
