Dreams about loved ones being harmed can be quite distressing and often reflect our subconscious fears and anxieties. In your dream, the act of your husband's friends poisoning him might symbolize feelings of distrust or concern you have regarding your husband's relationships or the influence of others in his life. It could also indicate a fear of betrayal or that you feel some external factors may harm your relationship.

Alternatively, this dream may not be about your husband or his friends specifically, but rather about feelings of vulnerability and the need to protect your loved ones. It’s important to reflect on your current feelings and any underlying issues you might be facing in your relationship or in your social circle.

Consider discussing your feelings with your husband to alleviate any worries and strengthen your connection. Remember, dreams can often serve as a way for our subconscious to process emotions and situations in our waking life.
