<human>: Can you provide a brief rundown of the text in within 3 sentences?

My roommate (new law student, 30yo) is finding her job incredibly stressful and suffered from insomnia. We've been living together for 7 months and have had lots of issues. Last night, it seems I woke her up as my friend and I are chatting in the living room (not loudly but we were still chatting). She was really passive aggressive about it and LOST HER SHIT in her room. She came out, smiled, and slammed the living door on us. Then she spent two hours SCREAMING her head off in her room calling me a c*** and just SCREAMING before going into hysterical crying. It is scary shit to hear it. I'm talking a 2-year-old-type tantrum coming out of a 30-year-old woman. I've never heard someone just scream at the top of their lungs. 

This is the second time it's happened. The first, I didn't know she had insomnia and I was talking to my bf in my room. And this time, I didn't know she was going to bed early otherwise I would have shut the door and kept it down. She's very passive aggressive in general so this time, I put in my headphones and ignored her.

I can't tell if her reaction is rational. Had anyone has any experience with insomnia?
<bot>: insomniac room mate flew into a rage and hysterics (screaming at the top of her lungs) when I accidently woke her up. Is this a rational reaction?
