Dehydration can frequently cause confusion and hallucinations if, of a high enough severity.
Dehydration can occur from:
• Excessive sweating
• physical activity
• heat
• illness
• not drinking enough fluids
• dysentery
• not drinking any fluids
• extreme cold
• not drinking at all
• dehydration
Any thoughts? I'm afraid Tony might be very thirsty and doesn't even know it because of the confusion.
