Tired and Unable to Sleep?

[tired_rn]

I'm a teen who is unable to sleep. I sometimes spend nights with very few hours of sleep (usually 2-5). The thing is: I fall asleep during the day excessively. When I do fall asleep at night, I get really bad nightmares that wake me up crying and screaming. Its been bothering me for nights and its terrifying. Lately, I've been hearing people call my name when I'm alone. I can't stand loud noise and lights hurt my eyes. I get irritated easily and once when I was asleep, I woke up in the kitchen with a full meal done. It was around 4 a.m. Another, I've woken up my sibling while I was unconscious and told that sibling to "Pick that up." He said I continuously told him to clean?
I was wondering what the hell is happening with me..
