The Complete Guide to Interpreting Your Dreams

by Stearn Robinson - Tom Corbett
Pins, as such, in a dream signify petty annoyances such as family squabbles, hurt pride, or minor disappointments; to dream of actually hearing the proverbial pin drop is a prophecy of contentment; sitting on a pin predicts a happy surprise; pinning up an article of clothing (Le., ladies’ dresses or mens’ slacks) forecasts a coming social embarrassment; to dream of swallowing a pin suggests that careless planning will lead you into an unpleasant situation, but a lucky circumstance will get you out; pricking yourself or being pricked by a pin (unless you sat on it) signifies that you will have to help cope with someone else’s problems; finding a pin is a sign of general good luck in all your current interests.

Ten Thousand Dream Dictionary

by Pamela Ball
1- It depends whether the pin is holding something together or is being used to pierce us, or an object, in our dreams.

If it is holding something together it indicates the emotional connections or bonds we use.

If it is piercing an object a trauma is suggested, although it may be quite small.

2- Occasionally in a dream we are reminded of a feeling we have in everyday life.

To experience a feeling of pins and needles in our dream suggests that we are not ensuring an adequate How of energy in a situation around us.

3- We may not be able to solve a spiritual difficulty immediately.

A temporary solution may be necessary and this can be symbolised by the use of a pin.

A pin might have several meanings. Pins are small tools that help us sew something together, so perhaps we are dreaming about knitting something together. Pins can also hold a notice to a bulletin board, so perhaps the dream is trying to call our attention to something. We sometimes talk about “pinning blame” or “pinning on hopes” on someone. We can also “pin something down” or “walk on pins and needles.”
