Tree-covered lay-by, suspicious activity

I stayed here for one night. 1. There was litter everywhere. 2. A strange man wearing black shoes, leggings or long cycling trousers, and a checked shirt. He walked around, including around my camper, and looked around strangely, as if searching for a place to urinate. As an emergency option you can stay here for one night, but preferably not alone.✦Translating
