So last night marked two Sundays in a row where I woke up feeling out of breath/suffocated and cause me to panic. The first time I was sleeping faced down with my arms under the pillow and woke up to a choking/suffocating feeling. I immediately rolled out of bed and tried to turn the lights on but my arms were asleep. Its a weird feeling because I felt like I was about to faint and my tongue was feeling like it was getting rolled up (similar to when I stutter). 

I made my way to the kitchen so at least I would make a noise if I passed out but eventually I felt well enough to get back to bed. 

Last night, I was feeling myself gradually fall asleep when I suddenly felt suffocated again and that falling-from-stairs dream feeling. I tried to go back to sleep several times and everytime I was beginning to fall asleep, it would happen again. Like something weighing on my chest. 

Prior to this I never ever had any of these symptoms. I am not sure what could be the cause. 

Nothing out of the ordinary stress from work, maybe caffeine from preworkout supplements but the worst Ive ever experienced was just lack of sleep. 

Any similar stories? I want to make sure I can describe it properly when I ask my Doctor.
