i saw a man put a black garbage bag by another man, tighten it on his neck and was turned upside down by the other man and killed him
This dream seems to be quite distressing and may indicate that you are feeling overwhelmed and helpless in some aspect of your life. The man with the black garbage bag could represent feelings of suffocation, burden, or negativity that you may be experiencing. The act of tightening the bag around the other man's neck and killing him could symbolize a sense of powerlessness or aggression towards a situation or person in your waking life. It is important to reflect on any recent events or relationships that may be causing you stress and try to address them in a healthy manner. Seeking support from loved ones or a therapist may also be beneficial.
