What does it mean when you dream about smoke?

To be surrounded by smoke in a dream indicates that the dreamer is suffering from confusion and anxiety. Often a dreamer will be choked and disoriented suggesting the need to “clear things up.”

(engineering)

Dispersions of finely divided (0.01-5.0 micrometers) solids or liquids in a gaseous medium.

smoke

1. An air suspension of particles, usually but not necessarily solid.

2. Carbon or soot particles less than 0.1 micron in size which result from the incomplete combustion of carbonaceous materials such as coal and oil.

smoke

As used in meteorology, it is small particles of carbonaceous material suspended in the air, which restrict visibility. The extent of obscurity is dependent on the amount of smoke particles and humidity, as the former serve as nuclei for the latter. Smoke is a residue from combustion.

(1)

To crash or blow up, usually spectacularly. "The new version smoked, just like the last one." Used for both hardware (where it often describes an actual physical event), and software (where it's merely colourful).

Smoke

 

a persistent dispersed system consisting of fine, solid particles in suspension in gases. Smoke is a typical aerosol with hard particles ranging from 10⁻⁷ to 10⁻⁵ m in size. As distinguished from dust (a more crudely dispersed system), smoke particles generally do not settle under the influence of gravity. Particles of smoke may serve as nuclei of condensation of atmospheric moisture, as a result of which fog develops. Smoke is produced, specifically, during combustion of fuel, for example, in furnaces of thermal electric power plants and various industrial units, and during fires, especially forest fires. Such smoke may contain large particles of unburned fuel and ashes, metallic oxides, soot, and tar. If flue gases are poorly cleaned, the immediate environment is polluted, the microclimate deteriorates, fog is formed, and natural illumination is reduced.

Smoke has a deleterious effect on man’s health, contributing to the development of such diseases as catarrhs of the upper respiratory tracts, bronchitis, and fibrous changes in the lungs. The presence of condensates of heavy metals (lead, mercury) in smoke causes blood changes and retardation in the physical development of children. Certain components of smoke contain carcinogenic substances, that is, those contributing to the development of tumors. Large particles, in entering the eye, damage the cornea and mucous membrane.

In order to combat smoke the heat and gas supply of enterprises and populated areas is centralized. In the USSR maximum permissible concentrations of noxious substances in the atmosphere have been established. Health-protection zones are being established, as are gas purification facilities. The decree of the Council of Ministers of the USSR of May 29, 1949, prohibits the operation of units that pollute the air without providing for purification of industrial emissions.

At the same time pesticide smoke is being employed in agriculture. Smoke produced in smoke generators is used in the curing of food products. Smoke is also utilized in military actions for smoke screens. Certain toxins are used in smoke form; special smoke filters are installed in gas masks for protection against these toxins.
