Mucus in dreams often symbolizes feelings of being overwhelmed or burdened by something hidden or unpleasant. It represents the need to release or cleanse oneself of negative emotions, thoughts, or situations that may be causing discomfort or unease. Dreaming of mucus may indicate a desire for emotional or physical purification and the need to address unresolved issues or problems. It can also reflect a need for better communication, as mucus can be associated with blocked or hindered expression. This dream invites the dreamer to take action in confronting and clearing away any obstacles or difficulties that are impeding personal growth or well-being.
