If you have a dream about having an ordinary limb amputation, this may simply reflect your fear of developing health disorders.
On a metaphorical level, which is more common when it comes to interpreting dream images and symbols, limb amputation may stand for your fear of losing something or someone you care about which is irreplaceable.
Amputation of limbs in dreams is generally a bad omen which may announce permanent loss of opportunities or regret about not fructifying certain aptitudes or talents.
When trying to 'decode' dreams of amputation we should be very careful about which limb is amputated and on which part of the body it is situated.
According to popular psychology, the right hemisphere of the brain is concerned with emotions and creativity, while the left cranial hemisphere deals more with logic and spatial reasoning. Taking into account the fact that our limbs are controlled by the brain, if in our dreams we have a right limb amputated this may mean that we are going to suffer emotional loss in the waking life - a break-up or a quarrel with someone we love. On the other hand, if a left limb is amputated in our dream, this points more to a loss or failure in career, business etc.
Moreover, dreaming that you have your hands amputated may have a different meaning as compared to dreaming that you have your legs amputated. The amputation of superior limbs is mostly related to coldness, lack of feelings (especially when having fingers removed) or lack of independence (not having a free hand.) On the other hand, the amputation of inferior limbs is mainly linked to 'limited movement', being trapped in an unpleasant situation. If the dream is mostly concerned with your soles or ankles, this points to having to face and overcome many obstacles in your waking life.
