After it was mentioned in a post the other day, I thought I'd say that last night i had a struggling to breathe dream ....something along the lines of going deep sea diving, only my air supply started to get cut off, anyway I normally stay asleep but last night I woke up and was actually struggling. I had an extremely tight chest and was having to use a lot of force to actually empty my lungs, anyway my pf was 280, that's only 49% for me! What's interesting is that I didn't wake until it was that low, do there's no wonder when I have asthma dreams and don't wake up, that I feel tired and drained!
Fortunately o eventually got it under control, and don't feel too bad this morning!
Ps Philomela if you read this, after you mentioned peak flow and doing it like blowing out candles, I get more reproducible results and the tend to reflect how im feeling a bit more, so thank you!
