Alter is a term used to describe the state of being changed or modified, and it can be used to refer to both drunkenness and hypnosis. Drunkenness is a state of intoxication caused by the consumption of alcohol, while hypnosis is a trance-like state in which a person is highly suggestible and open to suggestion. Both states ALTER a person's normal behavior and can have long-term effects on their mental and physical health.
