Abstinence 
To dream of abstaining can mean you are holding yourself back in life. Are you abstaining out of guilt, or are you practicing self-discipline? You may be missing out when you deserve to be enjoying. If you are abstaining to develop self-discipline, the dream reflects this.
There may be someone in your life that you would like more involvement with. You may feel this relationship is out of your power, but it is more likely that you are making a choice to abstain out of guilt, fear, or the unconscious knowledge that it is not right for you.
Vasectomy
To dream of receiving a vasectomy is a sign that you may be feeling a need to get back to your roots. There is an indication of 'tribe' here and a suggestion that connecting to the earth through 'drumming' or 'gardening', etc. may be helpful at this time.
To dream of fearing a vasectomy may be an indication that you are uncertain about an important decision and need to rethink it. Note the connections in your waking life. For example, if you or your partner is about to undergo a vasectomy and there are dreams of fear surrounding it, then this may be cause to discuss the matter before proceeding.
