These Three Sailors

last night I dreamed I was at my house, it looked like it was located in Cd. del Carmen at the oil company houses, in any case three sailors knocked on my door and asked to use the phone, they were very suspicious and I expected them to call their families or girlfriends, instead they started to send ciphered messages over the phone, like they were calling their base headquarters... maybe they were russian, I ve heard they dont give maintenance to their submarines, so maybe their radio didnt work...
