It is possible, it is something you can check with your doctor, on your next visit. This is one test, I do encourage - since most people are unaware they may have undiagnosed "Sleep Apnea" - like myself.
In my case, I was unaware of how often I would stop breathing during my sleep, until my wife would wake me up, because It appeared that I stopped breathing.
One of the things to mention to your doctor is this symptom, they can quickly diagnose if you indeed have 'sleep apnea' - which I found out in my case, was not associated with Panic Disorder, GAD, OCD or any other anxiety issue which I had already resolved.
Sleep Apnea Test - is an overnight test, in which they make sure that your brain is receiving enough oxygen during your sleep, since I snored a lot - my oxygen level to my brain was very low, and the sleeping diagnostic tools showed that I would wake up 18 times in 6 hours, without me ever knowing, which robs you of sleep and makes you very tired, never feeling rested.
Even if it is Sleep Apnea, THERE IS NO REASON TO BE ALARMED
, You're not going to die or stop breathing, (I had it for 30 years - and it was never diagnosed, until 2005).
Just as part of your stay healthy program, I would have my doctor run this test, just to rule it out, and if you have it - they have easy remedies for it, which will lead to a much healthier and better sleep for your overall health.
