as a matter of fact yes it can. low blood sugar definitely can make people hallucinate and do strange erratic things. however blood sugar has to be severely low to create bad dreams or hallucinations. anyone who has diabetes (or anyone with a family member who has diabetes) should be aware of the signs of low blood sugar. when a person has diabetes the focus tends to be on keeping blood sugar numbers down. but low blood sugar is a serious and even deadly possibly complication of diabetes. early signs of low blood sugar include: confusion shakiness weakness fainting hunger racing pulse anxiety and many others if you suspect low blood sugar and can take a blood glucose reading do so right away. if a person's blood sugar has fallen below 70 mg/dl give the person a small amount of sugar. monitor the individual carefully to ensure s/he doesn't develop signs of even lower blood sugar such as poor coordination and numbness of the mouth/tongue. if those symptoms occur call for emergency medical responders. otherwise take another blood glucose reading in an hour or so to make sure the level has risen above 70. if you have diabetes with frequent episodes of hypoglycemia (low blood sugar) see your doctor to learn how to control your diabetes better. wishing you well!
