fog, aggregation of water droplets or ice crystals immediately above the surface of the earth (i.e., a cloud near the ground). A light or thin fog is usually called a mist. Fog may occur when the moisture content of the air is increased beyond the saturation point. For example, fog usually results from the evaporation of warm water into cold air, which occurs when cold air streams over a warm water surface (steam fog) or when a warm rain falls through a layer of cold air near the ground (frontal fog). Fog also occurs when the air is cooled below a critical temperature called the dew point. Fog may be caused by radiation of heat from the ground during a windless, cloudless cool night (radiation fog); by the flow of warm air over a cold land or water surface (advection fog); or by air ascending a slope and cooling by expansion (upslope fog). In all cases condensation of the excess moisture takes place on the microscopic dust particles (condensation nuclei) in the atmosphere. Fog commonly found in valleys and depressions in the morning, especially during autumn, is of the radiation type, which because of its shallow nature is dissipated by the sun's heat as the day progresses. The extensive fog banks frequently occurring along the coasts of Newfoundland and Labrador are of the advective type and, being generally quite deep, often persist for days at a time, hindering shipping and aviation activity. In arid areas where fog is common, water may be harvested from the fog by using so-called fog nets or fog catchers.

Mist (pop culture)
In Bram Stoker‘s Dracula, Dr. Abraham Van Helsing, the vampire authority, suggested that vampires could transform into a mist, although their ability to travel very far in this form was quite limited. Dracula adopted this form to conceal himself on the ship Demeter while traveling to England. In this form, he could move with ease in and out of the box in which he rested. Van Helsing, acknowledging this ability, sealed the door of the vault of the vampirized Lucy Westenra‘s resting place with a putty containing flakes of a eucharistic wafer so not the tiniest space was left for her to escape. He later sealed the door to Castle Dracula in a similar manner.
Dracula’s primary appearances in the form of mist were during his attacks on Mina Murray. In Murray’s record of the first attack, she noted that she saw a thin streak of white mist that moved across the lawn. It seemed to have a sentience and vitality all its own. The mist started to move into the room, not through the window, but through the joinings of the door. The mist concentrated into a cloud out of which Dracula emerged. Several days later, when the men finally figured out that Murray was under attack, they went to her room and found her drinking Dracula’s blood. They moved toward him with crucifixes in hand, but he turned back into mist and disappeared under the door.
The idea of the vampire transforming into mist was a minor concept in folklore, but it was occasionally mentioned as a logical means for the vampire to leave and return from the grave without disturbing the topsoil that covered the coffin. The idea of such a transformation was often made when small holes apparently leading downward to the coffin lid appeared on the top of the grave.
In a famous moment from the fifth season of Buffy the Vampire Slayer, Buffy staked Dracula and then apparently left his Sunnydale lair. After a moment, Dracula began to reform from a mist. Buffy then quickly reentered the scene to stake him a second time, noting that she was aware of Dracula’s ability to revive from mist because she had watched him do this in the movies.

What does it mean when you dream about mist?
Mist or fog can symbolize a confused state of mind, as well as the desire to see things more clearly.

Fine liquid droplets suspended in or falling through a moving or stationary gas atmosphere.
A hydrometeor consisting of an aggregate of microscopic and more or less hygroscopic water droplets suspended in the atmosphere; it produces, generally, a thin, grayish veil over the landscape; it reduces visibility to a lesser extent than fog; the relative humidity with mist is often less than 95.
McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc.
The condition in which the horizontal visibility at the surface of the earth is between 3000 and
10,000 ft (1–3 km) because of suspended water droplets or ice crystals in the air. The relative humidity in mist is between 95 and 100%.

1. a thin fog resulting from condensation in the air near the earth's surface
2. Meteorol such an atmospheric condition with a horizontal visibility of 1--2 kilometres
3. Chem a colloidal suspension of a liquid in a gas
