Sleep Paralysis (Help?)

Date: 11/16/2016

I woke up at 2:20 to wish my girlfriend a great day as she had to get up early, and when I went back to sleep I tried to have a lucid dream by forcing sleep paralysis on myself. It worked except I had the feeling that I couldn't breath and it all went south. I conjured up my girlfriend in my mind and we both struggled to try and make me breathe. I woke up lurching for air, will reattempt tonight. Any suggestions on lucid dreaming where I won't feel like I'm dying?
