fog is a natural phenomenon. it usually appears in the morning, so people call it morning fog.

　　it is tuesday today. i got up very early to do some jogging as uaual. when i got out of the building. i found that i was surrounded by the fog. i didn't know whether i was in a dream or not, because everything was not clear. the street lights seemed far away, like stars in the sky.

　　i couldn't see anything or anybody three metres away. only could i hear some sounds. when people came nearer, i could see them clearly. my hair was wet. droplets were on my face.

　　the morning fog was gradually disappearing when the sun rose in he east. all the things were clear again.
