happens to me always, lol about the ciggie rolling....especially if they are blue rizlas!
I remember being out mushroom picking once, it was very foggy, and we were near a radio mast(Priddy, Somerset) I could here being repeated over and over (I assume a radio test)through the fog: Ice cream for tea, Over, ice cream for tea!
also when walking down the street or on the bus etc, I over hear things....
