Caught in the headlights

Whilst travelling late at the night last week I captured some images of something strange going on, which I want to share. We were driving quite slowly along a small dark road by the River Wensum near Ryburgh in Norfolk, not far from the B1146, when over a 2 km stretch of road we kept seeing and hearing some odd activity in the fields and undergrowth. I grabbed my old Pentax Me super SLR which was in the glove box (with black and white film) and started clicking away. We didnt want to stop. I have now had the film developed and printed and here are some of the pictures. I really dont know what was going on. We went back again the following night and all was calm and quiet.
