Have you ever experienced drowning in air?

This very early morning, I suddenly woke up gasping and choking and coughing a lot to be able to breathe. I thought I was drowning in air. It was a terrible experience. I was not having a nightmare but it was so sudden and my heartbeat was very fast. I thought I was already dying as it took me almost thirty seconds before I was able to cough out and take in air through my throat. I felt there was something or I think air which is blocking my throat and no matter how I breathe through my nose and my mouth I really can't breathe. Have you ever had that experience because I'm really afraid to experience that again. Do you think I have to see a doctor even if it just happened once? I will really appreciate any response.
