What does it mean when you dream about acid?

Can refer to something eating away at one’s insides. Alternatively, maybe an idea, a relationship, or a product is going through the “acid test.” Might also allude to an “acid tongue.”

acid

[′as·əd]
(chemistry)
Any of a class of chemical compounds whose aqueous solutions turn blue litmus paper red, react with and dissolve certain metals to form salts, and react with bases to form salts.
A compound capable of transferring a hydrogen ion in solution.
A substance that ionizes in solution to yield the positive ion of the solvent.
A molecule or ion that combines with another molecule or ion by forming a covalent bond with two electrons from the other species.

ACID

(programming)
A mnemonic for the properties a transaction should have to satisfy the Object Management Group Transaction Service specifications. A transaction should be Atomic, its result should be Consistent, Isolated (independent of other transactions) and Durable (its effect should be permanent).

The Transaction Service specifications which part of the Object Services, an adjunct to the CORBA specifications.

ACID

(Atomic, Consistent, Isolated, Durable) The properties of a transaction in a well-designed database management system (DBMS). The transaction must be ATOMIC (all updating tasks must be completed or nothing is done), CONSISTENT (it cannot leave the database in a state that violates any integrity rules), ISOLATED (remain invisible to other operations until completed) and DURABLE (will complete or be reversed if the system fails in the interim).
