A childhood belief about in the street

I used to believe that my neighbour across the street was a kidnapper and had all of my friends convinced of this also. He drove a massive Kenworth truck and I believed he stole children and kept them in the trailer end as prisoners. It got to the point where we'd hide under the coffee table or behind curtains when he arrived home from work every night. From then onwards I became paranoid about big trucks and shut my eyes when they went past at night with all the lights running down the side of the trailer. When my dad (who was friends with this man) found out what was going on he told me off for making up such rediculous stories. I honestly to this day don't remember making this up at all. The story just kind of appeared from no where.
