To dream of bleach represents a time of powerful healing and cleansing of personal issues. You may be trying to mend past hurts or resolve unexpressed emotions. A sign that you are undergoing big change, personal growth, or doing a lot of self-reflection.
Negatively, bleach may represent situations that you feel impose or pressure you into changing your bad habits. Self-control, respect for others, or bad habits that you feel you have to change.
