Dreams about walking with friends, particularly in dark and snowy settings, can often reflect feelings of vulnerability or uncertainty in your life. The darkness and snow may symbolize obstacles or challenges that you and your friends are facing together. The fact that you were walking under streetlights suggests you are seeking guidance or clarity in difficult situations.

The appearance of the random man could represent an external threat or a challenge that has suddenly emerged in your life. His question about who is the "most experienced" may indicate a situation where you feel pressured to identify skills or strengths within your group, perhaps reflecting a real-life scenario where you are evaluating your relationships or roles among your peers.

The chase in the dream signifies a sense of urgency or fear about an issue that you feel is closing in on you. Your instinct to keep your friends in front of you highlights your protective nature and concern for their safety, while also revealing your own feelings of inadequacy or fear of being left behind.

Overall, this dream may suggest that you are navigating through a phase of anxiety or stress, where you feel the need to rely on your friends for support. It could be beneficial to communicate with them about any concerns or pressures you are experiencing in your waking life. Building stronger connections and seeking guidance from those you trust can help you feel more secure as you face your challenges.
