Hello. My father is 70 years old and a diabetic. Usually sugar level ranging from 250 to 400. Recently he has developed some usual complication. He is getting hallucinations and often sees people standing in the corner or a bunch of people hiding behind the curtain and some insects crawling around or walking on his body. He sometimes even feels insects getting into his mouth. He also feels negativity at times. But otherwise apart from all this he is fine and talks normally. Please suggest as this is disturbing Thanks.
