The needle can often suggest masculine sexuality, but also the type of penetrating insight that changes our view of life. A sewing needle will suggest spiritual repair, a knitting needle may suggest creativity and a hypodermic healing, or sometimes self-harm.
In dreams hypodermic needles suggest irritations, but can also signify the power to heal through penetration. A concept or knowledge has to be introduced from the outside, which may hurt, but will ultimately improve our wellbeing.
