This dream may represent your fear of betrayal and deception from someone close to you. The man dressed up as a friend, then pulling out a knife and chasing you may symbolize someone you trust who will turn against you and harm you in some way. The long skyscrapers on both sides of the street may indicate feelings of being trapped and not being able to escape from the situation. This dream may be a warning sign to be cautious of people who seem friendly but could potentially hurt you in the future.
Additionally, the dream may also suggest that you are feeling vulnerable and exposed in your waking life, as being chased with a knife can represent feelings of danger and being threatened. This can be a reflection of a situation in your life where you feel you are not in control or where you are in danger and may need to take protective measures. It is important to identify any potential threats in your waking life and take steps to protect yourself if necessary.
