Ok so i have been dehydrated for the past few days and there have been times where i am in an hallucination and i am doing things i cant explain and then afterword i can barely remember what happened. I went to the doctor the other day and they told me i was moderately dehydrated and i should take it easy for a few days. but i was just wondering if my hallucinations have anything to do with my dehydration because this has never happened to me. also can dehydration cause migraines? been having those to.
