Hello, my name is Tony.I am 24 years old, smoker, a few drinks on the weekend, but other than that I am built like an ox. For about a year or two, right before I fall asleep, I have had this fluttering feeling in my head and chest right before I fall asleep. It is really hard to describe. I will be laying down fine, and then out of nowhere I feel almost like a rush come through my chest and move up to my head and then it "sounds" like a fluttering noise in my brain and then its gone. I say "sounds" because my wife cant hear it when it happens but I can. It is almost like the noise you hear when you yawn. Hopefully that makes some sort of sense to someone because it is really bothering me, almost to the point where I become afraid to try to fall back asleep. If anyone can help me at all I would really appreciate it.
