Is it normal to hear things that aren’t there from lack of sleep?
So this kinda started when I began college, and one time, I had pulled an all nighter, and for some reason, I thought I heard one of my roommates calling my name from outside my room. I went out, but there was nobody there, and when I questioned them about it in the morning, nobody knew anything about it. This happans to me once in a blue moon, but with different sounds (tv static, alarm clock, etc.) and every time, there’s no rational explanation for it. Is this a mild form of schizophrenia or something? Does this happen to everyone?
