leech,

predacious or parasitic annelid worm of the class Hirudinea, characterized by a cylindrical or slightly flattened body with suckers at either end for attaching to prey. The leech, like other annelids, is segmented, but its numerous surface folds obscure the internal segments. In many forms the mouth has three small jaws equipped with sharp teeth. The digestive tract has lateral pouches that hold enough of the leech's staple food, blood, to last for months. The reproductive system is complex; leeches are hermaphroditic and cross-fertilizing. Nearly all leeches are aquatic, abounding in freshwater ponds in temperate regions, but they also are found in the tropics, in polar oceans, and in deserts. Some are permanent parasites of humans, horses, cattle, fish, and mollusks, but most are merely predatory. The salivary secretions of the leech contain hirudin, an anticoagulant, and other substances that promote blood flow. The medicinal leech (Hirudo medicinalis), a European freshwater leech once used by physicians to bleed patients suffering from almost any ailment, are now used to remove pooled blood from under skin grafts and other reconstructive surgeries, to treat bruises (such as black eyes), and to treat some osteoarthritis. Certain small leeches of the E Mediterranean region may enter the bodies of humans and animals through drinking water and lodge as parasites in the mouth or the respiratory passages. The giant Amazon leech can grow as large as the forearm of an adult human being. Leeches are classified in the phylum AnnelidaAnnelida
[Lat., anellus=a ring], phylum of soft-bodied, bilaterally symmetrical (see symmetry, biological), segmented animals, known as the segmented, or annelid, worms.

Leech

(dreams)
Leeches are parasites that drain your energy and your resources. They are literally “bloodsuckers” and what they represent from your life is up to you to determine. Think about all of the draining things around you or inside of you. Usually dreams are designed to make us more aware of ourselves. Thus, the leeches may represent your own habits, thoughts, and negative emotions rather than someone in your environment. In the old days (and maybe in some remote parts of the world this is still happening) leeches were used frequently for medical purposes. They were harvested and used in case of infection, when a poisonous or harmful substance needed to be removed from the body. Maybe the leeches in your dream are there to suck out all of the negativity that you acquire throughout your day or in a particular situation.
