Dreaming of wearing all white often symbolizes purity, innocence, or a new beginning. The contrast of being in a super dark environment may suggest feelings of uncertainty, fear, or the unknown in your waking life. The bright light you saw can represent hope, guidance, or enlightenment, indicating that you are seeking clarity or direction amidst confusion.
This dream could be encouraging you to focus on positive aspects or new opportunities that may arise, even when things seem bleak. It might also suggest that you have the strength to find your way through difficult situations. Consider reflecting on any current challenges and how you can embrace positivity or find guidance in your life.
