This dream may reflect feelings of vulnerability and the need for self-protection in waking life. Walking on a road at night symbolizes a journey or path in life that may feel uncertain or dangerous. The car parked on the side of the road could represent a potential threat or obstacle. The man who approaches wanting you to get in may represent someone or something that is trying to lure you into a dangerous situation. Your refusal to get in and the use of a knife to defend yourself may suggest a strong sense of self-preservation and the ability to stand up for yourself. The fact that the man continues to approach despite the knife could symbolize a persistent threat or challenge in your life. The failed attempt to call for help may indicate a feeling of isolation or lack of support in dealing with this challenge. The lack of blood when stabbing the man could represent a sense of powerlessness or ineffectiveness in dealing with this threat. Overall, this dream may be a reflection of your inner strength and resilience in the face of adversity.
