<human>: Can you summarize the given text in a few sentences?

I'm a mid 30's male, healthy, 6'0" not overweight. As the title reads my throat closes during sleep and I can't breathe. It's happened before but this month has happened twice. Last time I had to crawl out of bed to get my roommate to help me. It's very scary and I never heard about this happening to anyone. 
I searched online and the most similar thing I found was "Obstructive Sleep Apnea" but I couldn't find anything about the throat's airway closing. 

Has anyone heard anything about this? 
Is there anything I can do to fix it? 
What could be causing this scary experience?

Thanks for helping
<bot>: My throat closes in my sleep leaving me gasping for air. Had to wake up my roommate because wasn't able to sleep for a scary amount of time.
