To dream of hearing howling may represent your sensitivity about a lingering threat or dangerous situation. Feeling that someone is trying to intimidate you or scare you away from something. Feeling that something is too dangerous to pursue right now.
Positively, howling may reflect someone or something in waking life that is warning you about potential vulnerabilities.
To dream that you are howling may represent you wish to project yourself as being too dangerous or threatening to others. Sending a message to others that it’s impossible for you to lose.
