why do i struggle to breath when i try to have a lucid dream it's when i'm staying still WTB method or w/e wake up then go t sleep method when I go to go back to sleep and stay still after a while i struggle to breath any ideas?

"I go to go back to sleep. and wake up then try to go back to sleep 30/60 mins later

After a while when im trying to get back to sleep my feet/hands tingle and so does some of my legs then I can't breathe I find it really hard to breath."

I wait till I'm tired then I just lay there and try to go to sleep I don't wake back up but I can't even do it when my breathing becomes difficult so I stop and try to get to sleep.
