Arson
To dream about an arson represents the rage within that has the potential to become destructive. It is best to express your anger instead of keeping it bottled up inside.
Machete
To see or use a machete in your dream, represents extreme hostility toward some situation or someone. It is symbolic of destruction and frustrations in your life. You are not expressing your anger in a productive way. In particular, if the machete is being used to clear through brush, then it refers to your ability to tackle problems successfully. Alternatively, the machete can be seen as a phallic symbol and thus represent masculine power.
Smoke
To see smoke in your dream indicates some sort of trouble that is entering your life. You are suffering from confusion and anxiety. In particular, if the smoke is black, then it means that you are not seeing some situation or problem clearly. If you dream of white smoke, then it implies that your emotions are clouding your judgment. Alternatively, white smoke symbolises an agreement or consensus.
Knitting
To dream that you are knitting signifies a quiet, peaceful and loving home life. It may also refer to someone in your life (past or present) who you associate with knitting. Alternatively, knitting symbolises your creativity or accomplishments. You need to take time out from your regular routine.
Porta Potty
To see or use a porta potty in your dream indicates that you need to express your feelings more openly. Don’t hold back your emotions. You need to let yourself go.
