Mom (94) is talking to invisible people about them eating and getting excited, breathing heavy. What do I do?

I agree, have her tested for a UTI. You do not mention any Dementia but this is a symptom. Moms Neurologist said not to worry about hallucinations if they don't scare her. Your Moms are upsetting her and causing anxiety, not good. Need to get her tova doctor.

Eas, if this is a sudden change in mental status for your mom, please get in touch with her doc adap.

She might have a urinary tract infection (uti) which can cause quite sudden changes like this.
