I just don't know what's going on. I haven't talked to a doctor about these yet and frankly I am afraid of going to the doctor about this. I do have irregular sleeping hours and all of these only occurs while sleeping.
About a year ago, I experienced something really weird. While sleeping, suddenly there's an intense pressure over the chest, kind of like strong winds blowing on the chest followed immediately by 2 sessions of discomfort in the chest area, not sure where, possibly the heart. It lasted around 5-10 seconds total, I couldn't speak or move while that was going on. But I am not sure if this even happened, it could just be a dream.
In the few months since then, I have had 3 seperate incidents of something similar that only happens if I put a blanket over my head and fall asleep. No pressure over the chest, just can't move for 5-10 seconds. If I try to breath deeply while that was going on, I would feel the air in my lungs not able to release.
So I stopped pulling the blanket over my head to stop those incidcents from occuring again. But now I am having those incidents again. In the past 2 months, I have had 2 (B) incidents again. Both times occuring just as I was lying on the bed, very relaxed, almost about to fall asleep. With the experiences, now I can feel when these incidents are about to start, I simply get off the bed before the incident starts to stop it from occuring.
I have had 1 incident of this, which happened about 3 weeks ago. No pressure over the chest, but extreme discomfort right under the left collar bone. Can't move or speak during the occurance. I continued sleeping. After I woke up, when I move my left arm, there would be minor discomfort under the left collar bone, this discomfort disappeared completely after 2 days.
