What do you suggest if my mom hallucinates after she has been drinking for 2 weeks why does she hallucinate when she not drunk?

She is having DTs: Withdrawal from heavy alcohol use can produce a variety of signs and symptoms, including seizures and hallucinations. Anyone drinking this much is endangering their health and their life. Your mother needs medical attention asap. If she is unwilling to get help, it may be at a point where involuntary commitment is necessary. Talk to other family members and seek legal advice if necessary.
