Acid

If you dream of chemicals or substances this dream suggests that emotion is important in your life. Acid is corrosive, therefore this indicates that you have a close relationship that may be destroyed.
Another meaning of this dream is that you feel a situation is slowly eating you away. Seems like things are getting worse, and you can't find a solution to it. If that is the case, then the message is to look within. The way you express yourself will be important to define and decide on the next course of action.
