fence

[short for defense], humanly erected barrier between two divisions of land, used to mark a legal or other boundary, to keep animals or people in or out, and sometimes as an ornament. In newly settled lands fences are usually made of materials at hand, e.g., stone, earth, or wood. A fence built of loose stones is called a dry-stone wall. Wooden fences may be built of boards, posts and rails, or pickets. Hardwoods such as oak and chestnut are preferred for fence posts, although softwoods treated with preservatives such as creosote may be used. Other fence materials are concrete, bricks, iron rails, woven wire, and barbed wirebarbed wire,
wire composed of two zinc-coated steel strands twisted together and having barbs spaced regularly along them. The need for barbed wire arose in the 19th cent.

ornamental or protective barrier composed of shrubs or small trees growing in close rows. The plants may be allowed to grow naturally or may be trimmed to various heights and shapes (see topiary work).

Fence

A structural barrier of wood or iron used to define, separate, or enclose areas like fields, yards, and gardens.

What does it mean when you dream about a fence?

A fence is a blockage, but it is also protection. Dream fences are sometimes symbolic of certain common verbal expressions, such as feeling “fenced in” and “straddling the fence.”

fence

fence
A stationary wall-like plate on the upper surface of a wing, extending chord-wise or substantially parallel to the airstream. Fences generally extend from one-third up to one-half of the wing chord and are located outward about two thirds of the span. Fences prevent a span-wise airflow, especially in swept wings. Also called a wing fence.

2. Machinery a guard or guide, esp in a circular saw or plane

fence

(1)
A sequence of one or more distinguished (out-of-band) characters (or other data items), used to delimit a piece of data intended to be treated as a unit (the computer-science literature calls this a "sentinel"). The NUL (ASCII 0000000) character that terminates strings in C is a fence. Hex FF is also (though slightly less frequently) used this way. See zigamorph.

fence

(2)
An extra data value inserted in an array or other data structure in order to allow some normal test on the array's contents also to function as a termination test. For example, a highly optimised routine for finding a value in an array might artificially place a copy of the value to be searched for after the last slot of the array, thus allowing the main search loop to search for the value without having to check at each pass whether the end of the array had been reached.

fence

(3)
[among users of optimising compilers] Any technique, usually exploiting knowledge about the compiler, that blocks certain optimisations. Used when explicit mechanisms are not available or are overkill. Typically a hack: "I call a dummy procedure there to force a flush of the optimiser's register-colouring info" can be expressed by the shorter "That's a fence procedure".

Fences

(dreams)
May represent your level of self-control. Maybe you need more or less of it. Additionally, this dream may express your need for privacy or connote feelings of being trapped. The details of this dream are vital to its interpretation, as is your general personality type. Are you very guarded or are you open emotionally and psychologically?
