Simone, the imagery in your dream is quite powerful and laden with significant emotional weight. The act of picking up used drug needles suggests a confrontation with past behaviors or habits that you may find regrettable or distressing. This imagery often symbolizes the process of cleaning up one's life or dealing with the aftermath of decisions that have had a profound impact on your mental and physical health.
The presence of your father in the dream is particularly noteworthy. Fathers often represent authority figures, guidance, or moral judgment in dreams. Your father watching you pick up used needles could indicate feelings of guilt, shame, or a fear of judgment regarding your past actions. It seems you might be experiencing an inner conflict about how your past choices are perceived by those you hold in high esteem or those who have had significant influence on your life.
This dream could also reflect a desire for approval or forgiveness from a father figure, suggesting unresolved issues or the need for reconciliation. The act of picking up the needles in his presence might be your subconscious way of seeking redemption or demonstrating that you are taking responsibility for your actions and attempting to make amends.
Additionally, the setting of the dream, where such a personal and vulnerable act occurs in front of someone significant, points to your inner struggle with vulnerability and exposure. It’s as if you are compelled to confront and clear out the remnants of your past in a very transparent and honest manner.
