To dream of a blow torch represents total discrimination or prejudice. An area of your life where specific requirements have to me met and anything less isn’t good enough. It may also represent rejection for anything less than perfect.
A blow torch may be a sign that you are demanding more of yourself, raising standards, or simply not interested in anything that is exactly what you want. It could also reflect a person or situation where negotiations or compromises are not possible.
Example: A young man dreamed with a blue flame. In real life his parents were very strict about who he was allowed to date. reflected the high degree of discrimination his parents had over his romantic life and their insensitive attitude toward anyone they didn’t approve of.
