Injection 

To dream that you are being injected for health reasons symbolizes the necessity of recovery. Your need for healing may encompass any aspect of your persona, mind, body, heart, and spirit.

To dream that someone is forcibly injecting you indicates your resistance and negative mindset about a particular situation or person. It also symbolizes the effect of peer pressure on you. You are aware that someone is pressing their negative and unsolicited advice and viewpoints on you.
